Abstract

The ENUBET ERC project (2016-2021) is studying a facility based on a narrow band beam capable of constraining the neutrino fluxes normalization through the monitoring of the associated charged leptons in an instrumented decay tunnel. A key element of the project is the design and optimization of the hadronic beamline. In this proceeding we present progress on the studies of the proton extraction schemes. We also show a realistic implementation and simulation of the beamline., Comment: Poster presented at NuPhys2019 (London, 16-18 December 2019). 4 pages, 4 figures. Typo in author list corrected

Abstract

The uncertainty in the initial neutrino flux is the main limitation for a precise determination of the absolute neutrino cross section. The ERC funded ENUBET project (2016-2021) is studying a facility based on a narrow band beam to produce an intense source of electron neutrinos with a ten-fold improvement in accuracy. Since March 2019 ENUBET is also a Neutrino Platform experiment at CERN: NP06/ENUBET. A key element of the project is the instrumentation of the decay tunnel to monitor large angle positrons produced together with $\nu_e$ in the three body decays of kaons ($K_{e3}$) and to discriminate them from neutral and charged pions. The need for an efficient and high purity e/$\pi$ separation over a length of several meters, and the requirements for fast response and radiation hardness imposed by the harsh beam environment, suggested the implementation of a longitudinally segmented Fe/scintillator calorimeter with a readout based on WLS fibers and SiPM detectors. An extensive experimental program through several test beam campaigns at the CERN-PS T9 beam line has been pursued on calorimeter prototypes, both with a shashlik and a lateral readout configuration. The latter, in which fibers collect the light from the side of the scintillator tiles, allows to place the light sensors away from the core of the calorimeter, thus reducing possible irradiation damages with respect to the shashlik design. This contribution will present the achievements of the prototyping activities carried out, together with irradiation tests made on the Silicon Photo-Multipliers. The results achieved so far pin down the technology of choice for the construction of the 3 m long demonstrator that will take data in 2021., Comment: Talk presented at the "15th Topical Seminar on Innovative Particle and Radiation Detectors (IPRD19)", 14-17 October 2019.

Abstract

We present the first application of polysiloxane-based scintillators as active medium in a shashlik sampling calorimeter. These results were obtained from a testbeam campaign of a $\sim$6$\times$6$\times$45 cm$^3$ (13 $X_0$ depth) prototype. A Wavelength Shifting fiber array of 36 elements runs perpendicularly to the stack of iron (15 mm) and polysiloxane scintillator (15 mm) tiles with a density of about one over cm$^2$. Unlike shashlik calorimeters based on plastic organic scintillators, here fibers are optically matched with the scintillator without any intermediate air gap. The prototype features a compact light readout based on Silicon Photo-Multipliers embedded in the bulk of the detector. The detector was tested with electrons, pions and muons with energies ranging from 1 to 7 GeV at the CERN-PS. This solution offers a highly radiation hard detector to instrument the decay region of a neutrino beam, providing an event-by-event measurement of high-angle decay products associated with neutrino production (ENUBET, Enhanced NeUtrino BEams from kaon Tagging, ERC project). The results in terms of light yield, uniformity and energy resolution, are compared to a similar calorimeter built with ordinary plastic scintillators., Comment: 28 pages, 16 figures.

Abstract

The narrow band beam of ENUBET is the first implementation of the "monitored neutrino beam" technique proposed in 2015. ENUBET has been designed to monitor lepton production in the decay tunnel of neutrino beams and to provide a 1% measurement of the neutrino flux at source. In particular, the three body semi-leptonic decay of kaons monitored by large angle positron production offers a fully controlled $\nu_{e}$ source at the GeV scale for a new generation of short baseline experiments. In this contribution the performances of the positron tagger prototypes tested at CERN beamlines in 2016-2018 are presented., Comment: Poster presented at NuPhys2018 (London 19-21 December 2018). 5 pages, 3 figures

Abstract

The ENUBET ERC project (2016-2021) is studying a narrow band neutrino beam where lepton production can be monitored at single particle level in an instrumented decay tunnel. This would allow to measure $\nu_{\mu}$ and $\nu_{e}$ cross sections with a precision improved by about one order of magnitude compared to present results. In this proceeding we describe a first realistic design of the hadron beamline based on a dipole coupled to a pair of quadrupole triplets along with the optimisation guidelines and the results of a simulation based on G4beamline. A static focusing design, though less efficient than a horn-based solution, results several times more efficient than originally expected. It works with slow proton extractions reducing drastically pile-up effects in the decay tunnel and it paves the way towards a time-tagged neutrino beam. On the other hand a horn-based transferline would ensure higher yields at the tunnel entrance. The first studies conducted at CERN to implement the synchronization between a few ms proton extraction and a horn pulse of 2-10 ms are also described., Comment: Poster presented at NuPhys2018 (London 19-21 December 2018). 4 pages, 3 figures

Abstract

The current generation of short baseline neutrino experiments is approaching intrinsic source limitations in the knowledge of flux, initial neutrino energy and flavor. A dedicated facility based on conventional accelerator techniques and existing infrastructures designed to overcome these impediments would have a remarkable impact on the entire field of neutrino oscillation physics. It would improve by about one order of magnitude the precision on $\nu_\mu$ and $\nu_e$ cross sections, enable the study of electroweak nuclear physics at the GeV scale with unprecedented resolution and advance searches for physics beyond the three-neutrino paradigm. In turn, these results would enhance the physics reach of the next generation long baseline experiments (DUNE and Hyper-Kamiokande) on CP violation and their sensitivity to new physics. In this document, we present the physics case and technology challenge of high precision neutrino beams based on the results achieved by the ENUBET Collaboration in 2016-2018. We also set the R&D milestones to enable the construction and running of this new generation of experiments well before the start of the DUNE and Hyper-Kamiokande data taking. We discuss the implementation of this new facility at three different level of complexity: $\nu_\mu$ narrow band beams, $\nu_e$ monitored beams and tagged neutrino beams. We also consider a site specific implementation based on the CERN-SPS proton driver providing a fully controlled neutrino source to the ProtoDUNE detectors at CERN., Comment: 13 pages, 3 figures, submitted as an input document for the European Particle Physics Strategy.

Abstract

The production of flexible and robust thermal neutron detectors with improved properties as compared to the commercial ZnS:Ag based phosphors is here pursued, exploiting a siloxane binder, whose intrinsic properties as related to the chemical features of the functional groups and to the optical properties are investigated and tailored in correlation with the final performances of the detectors. Two different siloxanes either with pendant phenyl groups or with aliphatic groups have been used, the former being intrinsically fluorescent and with higher polarizability than the latter. Moreover, 6LiF crystals have been synthesized by co-precipitation method and the solvent/co-solvent ratio has been changed in order to tune the crystal size. Then, the size effect on the detector efficiency to thermal neutrons has been investigated as related to the energy loss of thermal neutron reaction products inside the crystal and the dispersion homogeneity of the crystals into the composite. To complete the characterization of the produced flexible detectors, the response to {\gamma}-rays has been measured and compared to a commercial detector. The careful choice of both the base resin and the 6LiF crystals size allows to produce flexible detector for thermal neutrons with performances comparable to the commercial standard and with higher mechanical robustness and stability., Comment: submitted to European Physical Journal A, EPJA-104631, currently under review

Abstract

The ENUBET facility is a proposed narrow band neutrino beam where lepton production is monitored at single particle level in the instrumented decay tunnel. This facility addresses simultaneously the two most important challenges for the next generation of cross section experiments: a superior control of the flux and flavor composition at source and a high level of tunability and precision in the selection of the energy of the outcoming neutrinos. We report here the latest results in the development and test of the instrumentation for the decay tunnel. Special emphasis is given to irradiation tests of the photo-sensors performed at INFN-LNL and CERN in 2017 and to the first application of polysiloxane-based scintillators in high energy physics., Comment: Poster presented at NuPhys2017 (London, 20-22 December 2017). 5 pages, 2 figures

Abstract

The CERN NP06/ENUBET experiment is designing the first “monitored neutrino beam”, i.e. a neutrino beam with unprecedented control of the flux, energy and flavor of the neutrinos at source. The original aim of ENUBET was to monitor the ?e production mostly by the detection of large-angle positrons from three-body semileptonic decays of kaons: K+ ? e+p0?e. Over the years, the ENUBET technique has been extended to cover also the monitoring of the ?µ from kaon and pion decays. In this paper, we present these new developments and the overall status of the project.

Abstract

The ENUBET ERC project (2016-2021) is studying a narrow band neutrino beam where lepton production can be monitored at single particle level. For this purpose, the decay tunnel is instrumented with longitudinally segmented calorimeters. Three different specialized calorimeters have been designed and tested, two of which based on the shashlik calorimetric concept with a compact readout while the third is a less compact version with a lateral readout. All of the prototypes are composed of thick steel absorbers coupled to plastic scintillators. Regarding the shashlik modules, a matrix of 3 x 3 fibers runs transversely with a density of one fiber/cm(2). The fibers are coupled individually to silicon photomultipliers mounted on a custom PCB allowing to reduce the dead zones between adjacent modules to an extremely small level compared to the "fiber bundling" configurations. This setup allows a very effective longitudinal segmentation and hence e/pi separation. The second shashlik module is based on polysiloxane scintillators which come in liquid form, are poured around the fiber arrays and finally made solid with a thermal treatment. Finally, the lateral readout module, light is collected from both sides of each scintillator tile and the 10 fibers from the same UCM are bundled to a single SiPM. Here are discussed the results of test beams performed in 2016-2018 at the CERN-PS East Area and the characterization of SiPMs of different cell size (12 mu m and 15 mu m) before and after being exposed to neutron fluxes up to 10(12)/cm(2) at the INFN-LNL CN accelerator facility.

Abstract

We present the first application of polysiloxane-based scintillators as active medium in a shashlik sampling calorimeter. These results were obtained from a testbeam campaign of a ∼6×6×45 cm3 (13 X0 depth) prototype. A Wavelength Shifting fiber array of 36 elements runs perpendicularly to the stack of iron (15 mm) and polysiloxane scintillator (15 mm) tiles with a density of about one over cm2. Unlike shashlik calorimeters based on plastic organic scintillators, here fibers are optically matched with the scintillator without any intermediate air gap. The prototype features a compact light readout based on Silicon Photo-Multipliers embedded in the bulk of the detector. The detector was tested with electrons, pions and muons with energies ranging from 1 to 7 GeV at the CERN-PS. This solution offers a highly radiation hard detector to instrument the decay region of a neutrino beam, providing an event-by-event measurement of high-angle decay products associated with neutrino production (ENUBET, Enhanced NeUtrino BEams from kaon Tagging, ERC project). The results in terms of light yield, uniformity and energy resolution, are compared to a similar calorimeter built with ordinary plastic scintillators.

Abstract

Shashlik calorimeters equipped with a compact readout based on Silicon PhotoMultipliers can be longitudinally segmented by directly coupling the WLS fibers with the photosensors thus embedding the readout in the bulk of the calorimeter. Results on energy resolution and particle identification for such calorimeters are presented. The SiPMs for the readout have also been characterized after being exposed to neutron fluences up to 2×1011 n/cm2 (1 MeV eq.). Alternative options for the active material were also investigated; we studied in particular polysiloxane as a substitute for plastic scintillator

Abstract

International audience; ENUBET has been designed to monitor lepton production in the decay tunnel of neutrino beams at single particle level and to provide a 1% measurement of the neutrino flux at source. In particular, the three body semileptonic decay of kaons monitored by large angle positron production offers a fully controlled $\nu_e$ source at the GeV scale for a new generation of short baseline experiments. The ENUBET Collaboration presented at ICHEP the first end-to-end simulation of the beamline and a review of the performance of this non-conventional technique. Special emphasis has been given to the new static focusing system that was validated in 2018. We also discussed the performance of the positron tagger tested at CERN in 2017-2018 and the expected sensitivity of ENUBET for $\nu_e$ and $\nu_\mu$ events.

Abstract

International audience; The knowledge of initial flux, energy and flavour of current neutrino beams is currently the main limitation for a precise measurement of neutrino crosssections. The ENUBET ERC project (2016–2021) is studying a facility based on a narrow-band neutrino beam capable of constraining the neutrino flux normalization through the monitoring of the associated charged leptons in an instrumented decay tunnel. In particular, the identification of large-angle positrons from Ke3 decays at single-particle level can reduce the νe flux uncertainty at the level of 1%. This setup would allow for an unprecedented measurement of the νe cross-section at the GeV scale. Such an experimental input would be highly beneficial to reduce the budget of systematic uncertainties in the next long baseline oscillation projects (i.e., HyperK-DUNE). Furthermore, in narrow-band beams, the transverse position of the neutrino interaction at the detector can be exploited to determine a priori with significant precision the neutrino energy spectrum without relying on the finalstate reconstruction.

Abstract

Shashlik calorimeters are sampling calorimeters using wavelength shifting fibers running perpendicularly to the scintillating/absorber plates for the light readout. These devices are cost-effective, easy to assemble, and characterized by a good flexibility in terms of energy resolution. On the contrary, the perpendicular optical fiber readout and the resulting fiber bundling to the photosensor pose a strong limitation to the longitudinal segmentation. Recently, the fast development of solid state photosensors allowed for the integration of the readout system directly in the bulk of the calorimeter, opening new possibilities in terms of longitudinal segmentation (SCENTT INFN R D). In an ultra-compact module every single fiber segment is directly connected to a SiPM; the SiPMs are arranged in arrays on custom PCBs and readout by a fast electronics based on waveform digitizers. This detector technology is the baseline option for ENUBET: a 5 year project (2016-2021) funded by the European Research Council aiming to demonstrate the possibility of a complete instrumentation of the decay tunnel of conventional neutrino beam. This technique allows for a ten-fold reduction on the neutrino flux normalization error. In the talk we will present the results and a detailed performance assessment of the novel ultra-compact design obtained with a prototype of longitudinally segmented shashlik calorimeter, readout with SiPMs embedded in the calorimeter bulk. Tests performed at the CERN PST9 beamline in the 1-5 GeV energy range in November 2016 provided results in terms of linearity, energy resolution and e/pi discrimination at various beam angles reproducing the grazing incident conditions typical of neutrino beam decay tunnels. We will also present results from a neutron irradiation campaign of our Silicon Photomultipliers at the INFN-LNL CN accelerator allowing to test neutron fluences of O(10^12/cm^2) using 5 MeV protons on a Be target.

Abstract

The knowledge of initial flux, energy and flavour of current neutrino beams is currently the main limitation for a precise measurement of neutrino crosssections. The ENUBET ERC project (2016-2021) is studying a facility based on a narrow-band neutrino beam capable of constraining the neutrino flux normalization through the monitoring of the associated charged leptons in an instrumented decay tunnel. In particular, the identification of large-angle positrons from K-e3 decays at single-particle level can reduce the v(e) flux uncertainty at the level of 1%. This setup would allow for an unprecedented measurement of the v(e) cross-section at the GeV scale. Such an experimental input would be highly beneficial to reduce the budget of systematic uncertainties in the next long baseline oscillation projects (i.e., HyperK-DUNE). Furthermore, in narrow-band beams, the transverse position of the neutrino interaction at the detector can be exploited to determine a priori with significant precision the neutrino energy spectrum without relying on the final-state reconstruction.

Abstract

International audience; Neutrino fluxes are currently affected by large normalization uncertainties (5-10%). Neutrino physics will require measurements of absolute neutrino cross sections at the GeV scale with exquisite (1%) precision in the near future. For this reason a reduction of the present uncertainties by one order of magnitude would be highly beneficial. This goal might be achieved by producing a sign and momentum selected narrow band beam and monitoring the production of $e^{+}$ in the decay tunnel from the decays of charged Kaons ($K_{e3}$ channel). This technique, which requires a special instrumented beam-line, would allow a 1% level measurement of the cross-sections of the neutrino species ($\nu_e$ and $\bar{\nu}_e$) which are the final states involved in the searches for CP violation with muon neutrino beams at long-baseline. The ENUBET Horizon-2020 ERC Consolidator Grant, approved by the European Research Council in 2015, is the framework within which such a non conventional beam-line will be developed. We present a progress report of the project (2016-2021) after about one year of work, the experimental results on ultra-compact calorimeters suited for the instrumenting the decay tunnel and the R&D in the design of the hadronic beamline.

Abstract

The knowledge of the initial flux in conventional neutrino beams represents the main limitation for a precision (1\%) measurement of $\nu_e$ and $\nu_\mu$ cross sections. Since 2016, ENUBET has achieved remarkable results in the design of a neutrino beam with superior control of the fluxes and has extended its physics case to cover all the needs of new generation cross section experiments. In this Proposal, we summarize the achievement of ENUBET in the design and simulation of the proton extraction scheme, focusing system, transfer line and instrumentation of the decay tunnel. We present the results on positron reconstruction from the $K_{e3}$ decays and the impact on the determination of the flux, outlining the activities that will be carried on during LS2 and the final validation of the ENUBET demonstrator in 2021. Special emphasis will be given on the activities that will be performed in collaboration with the CERN groups and the use of CERN facilities and infrastructures. In the Proposal, we also discuss the potential of monitored neutrino beams beyond the original aim of ENUBET: the flux measurement at the 1\% level for all $\nu_\mu$ produced in the beam and the determination of the neutrino energy without relying on final state particle reconstruction. In addition, the ENUBET static focusing system paves the way to the construction of a tagged neutrino beam, i.e. a facility where the observation of the lepton in the decay tunnel is associated with the neutrino scattering in the neutrino detector on an event-by-event basis. Perspectives and opportunities offered by tagged neutrino beams are discussed, too.

Abstract

The ENUBET project aims at demonstrating that the systematics in neutrino fluxes from conventional beams can be reduced to 1% by monitoring positrons from Ke 3 decays in an instrumented decay tunnel, thus allowing a precise measurement of the ve (and ve) cross section. This contribution will report the results achieved in the first year of activities. The expected neutrino fluxes at an hypothetical far detector have been estimated. Progress have been made in the design of the hadron beamline and a complete simulation of the positron tagger allowed to determine its performance in terms of signal selection efficiency and purity. A deep R&D program has been pursued to explore different technical solution for the tagger instrumentation. Test beam exposures of detector prototypes have been performed to assess their response to pions, electrons and muons and to validate the Monte Carlo simulation.

Abstract

In this work, first results on newly developed thermal neutrons scintillators are reported. The main focus is the synthesis and characterization of 6LiF nanoparticles, to be added to the polysiloxane matrix as neutron absorber. The preparation of 6LiF nanocrystals has been pursued by co-precipitation technique, using a mixture of water and ethanol in different ratios. The as-prepared nanocrystals have been characterized in terms of crystal structure and crystallite size by X-ray diffraction, whereas the composition has been investigated by energy dispersive spectroscopy. In this preliminary step towards the realization of a new detector, the commercial inorganic phosphor ZnS:Ag (EJ-600) has been used as scintillating medium. A fixed weight ratio of 6LiF nanocrystals and EJ-600 phosphor has been chosen, namely 3:1 EJ-600:6LiF, whereas different amounts of the mixture have been added to the polysiloxane binder, prior to cross-linking. The composites have been benchmarked as for light output and thermal neutrons detection efficiency against a commercial sample of EJ-426 taken as a reference. [ABSTRACT FROM AUTHOR]

Abstract

International audience; The ENUBET project is studying a narrow band neutrino beam where lepton production can be monitored at single particle level in an instrumented decay tunnel and that could provide a 1% measurement of the neutrino flux at source. The three body semi-leptonic decay of kaons monitored by large angle positron production offers a fully controlled $\nu_{e}$ source at the GeV scale for a new generation of short baseline experiments. The ENUBET Collaboration presented at NuFact2018 the first end-to-end simulation of the beamline, the physics performance and the results of the test beam performed on the positron tagger. We reported ENUBET expected fluxes for $\nu_{e}$ and $\nu_{\mu}$

Abstract

The ENUBET facility is a proposed narrow band neutrino beam where lepton production is monitored at single particle level in the instrumented decay tunnel. This facility addresses simultaneously the two most important challenges for the next generation of cross section experiments: a superior control of the flux and flavor composition at source and a high level of tunability and precision in the selection of the energy of the outcoming neutrinos. We report here the latest results in the development and test of the instrumentation for the decay tunnel. Special emphasis is given to irradiation tests of the photo-sensors performed at INFN-LNL and CERN in 2017 and to the first application of polysiloxane-based scintillators in high energy physics., Poster presented at NuPhys2017 (London, 20-22 December 2017). 5 pages, 2 figures

Abstract

The ENUBET ERC project (2016–2021) is studying a narrow band neutrino beam where lepton production can be monitored at single particle level. For this purpose, the decay tunnel is instrumented with longitudinally segmented calorimeters. Three different specialized calorimeters have been designed and tested, two of which based on the shashlik calorimetric concept with a compact readout while the third is a less compact version with a lateral readout. All of the prototypes are composed of thick steel absorbers coupled to plastic scintillators. Regarding the shashlik modules, a matrix of 3 × 3 fibers runs transversely with a density of one fiber/cm2. The fibers are coupled individually to silicon photomultipliers mounted on a custom PCB allowing to reduce the dead zones between adjacent modules to an extremely small level compared to the “fiber bundling” configurations. This setup allows a very effective longitudinal segmentation and hence e / π separation. The second shashlik module is based on polysiloxane scintillators which come in liquid form, are poured around the fiber arrays and finally made solid with a thermal treatment. Finally, the lateral readout module, light is collected from both sides of each scintillator tile and the 10 fibers from the same UCM are bundled to a single SiPM. Here are discussed the results of test beams performed in 2016–2018 at the CERN-PS East Area and the characterization of SiPMs of different cell size ( 12 μ m and 15 μ m ) before and after being exposed to neutron fluxes up to 1012/cm2 at the INFN-LNL CN accelerator facility.

Abstract

The goal of the ENUBET project is to demonstrate that a precision of ∼ 1 % on measurement of the absolute neutrino cross section at GeV scale can be achieved by monitoring the positron production in the decay tunnel coming from the three-body semileptonic decays of kaons. The baseline option for the tunnel instrumentation employs a fine-grained shashlik calorimeter with a 4.3 X0 longitudinal segmentation to separate positrons and pions coming from other decay modes of kaons. The system is complemented by rings of plastic scintillator doublets below the calorimeter acting as a photon veto to suppress the π 0 background and to provide timing informations. SiPMs instrumenting the detector will be exposed to sizeble amounts of neutrons arising in hadronic showers. In order to reproduce such a working environment, SiPMs with different cell size (from 12 to 20 μ m ) were irradiated at the INFN-LNL CN Van Der Graaf with neutron fluences up to 2 × 10 11 n/cm2 (1 MeV-eq.). The exposed light sensors were characterized in terms of I–V curves at different irradiation levels, and their response tested by exposing a prototype on beam at CERN. In this contribution we will report the results of the described tests on SiPMs, together with the advances in their integration with the ENUBET detectors.

Abstract

The knowledge of the initial flux, energy and flavor of current neutrino beams is the main limitation for a precise measurement of neutrino cross-sections. The ENUBET ERC project is studying a facility based on a narrow-band neutrino beam capable of constraining the neutrino fluxes normalization through the monitoring of the associated charged leptons in an instrumented decay tunnel. In ENUBET, the identification of large-angle positrons from [Formula: see text] decays at single particle level can potentially reduce the [Formula: see text] flux uncertainty at the level of 1%. This setup would allow for an unprecedented measurement of the [Formula: see text] cross-section at the GeV scale. This input would be highly beneficial to reduce the budget of systematic uncertainties in the next long baseline oscillation projects. Furthermore, in narrow-band beams, the transverse position of the neutrino interaction at the detector can be exploited to determine a priori with significant precision the neutrino energy spectrum without relying on the final state reconstruction. This contribution will present the advances in the design and simulation of the hadronic beam line. Special emphasis will be given to a static focusing system of secondary mesons that can be coupled to a slow extraction proton scheme. The consequent reduction of particle rates and pile-up effects makes the determination of the [Formula: see text] flux through a direct monitoring of muons after the hadron dump viable, and paves the way to a time-tagged neutrino beam. Time-coincidences among the lepton at the source and the neutrino at the detector would enable an unprecedented purity and the possibility to reconstruct the neutrino kinematics at source on an event-by-event basis. We will also present the performance of positron tagger prototypes tested at CERN beamlines, a full simulation of the positron reconstruction chain and the expected physics reach of ENUBET.

Abstract

We present the first application of polysiloxane-based scintillators as active medium in a shashlik sampling calorimeter. These results were obtained from a testbeam campaign of a $\sim$6$\times$6$\times$45 cm$^3$ (13 $X_0$ depth) prototype. A Wavelength Shifting fiber array of 36 elements runs perpendicularly to the stack of iron (15 mm) and polysiloxane scintillator (15 mm) tiles with a density of about one over cm$^2$. Unlike shashlik calorimeters based on plastic organic scintillators, here fibers are optically matched with the scintillator without any intermediate air gap. The prototype features a compact light readout based on Silicon Photo-Multipliers embedded in the bulk of the detector. The detector was tested with electrons, pions and muons with energies ranging from 1 to 7 GeV at the CERN-PS. This solution offers a highly radiation hard detector to instrument the decay region of a neutrino beam, providing an event-by-event measurement of high-angle decay products associated with neutrino production (ENUBET, Enhanced NeUtrino BEams from kaon Tagging, ERC project). The results in terms of light yield, uniformity and energy resolution, are compared to a similar calorimeter built with ordinary plastic scintillators., Comment: 28 pages, 16 figures.

Abstract

The uncertainty in the initial neutrino flux is the main limitation for a precise determination of the absolute neutrino cross section. The ERC funded ENUBET project (2016-2021) is studying a facility based on a narrow band beam to produce an intense source of electron neutrinos with a ten-fold improvement in accuracy. Since March 2019 ENUBET is also a Neutrino Platform experiment at CERN: NP06/ENUBET. A key element of the project is the instrumentation of the decay tunnel to monitor large angle positrons produced together with $\nu_e$ in the three body decays of kaons ($K_{e3}$) and to discriminate them from neutral and charged pions. The need for an efficient and high purity e/$\pi$ separation over a length of several meters, and the requirements for fast response and radiation hardness imposed by the harsh beam environment, suggested the implementation of a longitudinally segmented Fe/scintillator calorimeter with a readout based on WLS fibers and SiPM detectors. An extensive experimental program through several test beam campaigns at the CERN-PS T9 beam line has been pursued on calorimeter prototypes, both with a shashlik and a lateral readout configuration. The latter, in which fibers collect the light from the side of the scintillator tiles, allows to place the light sensors away from the core of the calorimeter, thus reducing possible irradiation damages with respect to the shashlik design. This contribution will present the achievements of the prototyping activities carried out, together with irradiation tests made on the Silicon Photo-Multipliers. The results achieved so far pin down the technology of choice for the construction of the 3 m long demonstrator that will take data in 2021., Comment: Talk presented at the "15th Topical Seminar on Innovative Particle and Radiation Detectors (IPRD19)", 14-17 October 2019.

Abstract

International audience; Shashlik calorimeters equipped with a compact readout based on Silicon PhotoMultipliers can be longitudinally segmented by directly coupling the WLS fibers with the photosensors thus embedding the readout in the bulk of the calorimeter. Results on energy resolution and particle identification for such calorimeters are presented. The SiPMs for the readout have also been characterized after being exposed to neutron fluences up to 2×10$^{11}$ n/cm$^2$ (1 MeV eq.). Alternative options for the active material were also investigated; we studied in particular polysiloxane as a substitute for plastic scintillator.

Abstract

The ENUBET project is studying a narrow band neutrino beam where lepton production can be monitored at single particle level in an instrumented decay tunnel and that could provide a 1% measurement of the neutrino flux at source. The three body semi-leptonic decay of kaons monitored by large angle positron production offers a fully controlled $\nu_{e}$ source at the GeV scale for a new generation of short baseline experiments. The ENUBET Collaboration presented at NuFact2018 the first end-to-end simulation of the beamline, the physics performance and the results of the test beam performed on the positron tagger. We reported ENUBET expected fluxes for $\nu_{e}$ and $\nu_{\mu}$

Abstract

International audience; Shashlik calorimeters are sampling calorimeters using wavelength shifting fibers running perpendicularly to the scintillating/absorber plates for the light readout. These devices are cost-effective, easy to assemble, and characterized by a good flexibility in terms of energy resolution. On the contrary, the perpendicular optical fiber readout and the resulting fiber bundling to the photosensor pose a strong limitation to the longitudinal segmentation. Recently, the fast development of solid state photosensors allowed for the integration of the readout system directly in the bulk of the calorimeter, opening new possibilities in terms of longitudinal segmentation (SCENTT INFN R &D). In an ultra-compact module every single fiber segment is directly connected to a SiPM; the SiPMs are arranged in arrays on custom PCBs and readout by a fast electronics based on waveform digitizers. This detector technology is the baseline option for ENUBET: a 5 year project (2016-2021) funded by the European Research Council aiming to demonstrate the possibility of a complete instrumentation of the decay tunnel of conventional neutrino beam. This technique allows for a ten-fold reduction on the neutrino flux normalization error. In the talk we will present the results and a detailed performance assessment of the novel ultra-compact design obtained with a prototype of longitudinally segmented shashlik calorimeter, readout with SiPMs embedded in the calorimeter bulk. Tests performed at the CERN PST9 beamline in the 1-5 GeV energy range in November 2016 provided results in terms of linearity, energy resolution and e/π discrimination at various beam angles reproducing the grazing incident conditions typical of neutrino beam decay tunnels. We will also present results from a neutron irradiation campaign of our Silicon Photomultipliers at the INFN-LNL CN accelerator allowing to test neutron fluences of O(1012/cm2) using 5 MeV protons on a Be target.

Abstract

International audience; The next generation of neutrino experiments requires measurements of absolute neutrino cross sections at the GeV scale with high precision (∼1%) presently limited by the uncertainties on neutrino flux. Monitoring the lepton production in the decay tunnel of neutrino beams is the most straightforward way to measure the neutrino flux at source. The ENUBET Collaboration develops novel technologies to monitor positrons from K + → νee +π0 decays on an event by event basis. This technique can achieve a precision in the νe flux below 1% and enable a new generation of cross section and short baseline experiments. In this paper, we present the achievements of the first year of the Project on beamline simulation, rate and dose assessment, detector prototyping and evaluation of the physics reach.

Abstract

Sono trascorsi ormai trent’anni dagli importanti contributi monografici offerti da Guido Tadini sulla figura complessa e affascinante di Antonio Ferramolino da Bergamo, di certo uno dei più autorevoli ingegneri militari al servizio della monarchia spagnola nel Mediterraneo del primo Cinquecento. Sebbene gli studi più recenti, in particolar modo quelli sull’ingegnere Pietro Antonio Tomasello da Padova, suo predecessore, abbiano in parte ridimensionato quel ruolo “pionieristico” nel processo di potenziamento delle difese siciliane che la storiografia gli aveva attribuito, resta indubbio come la figura di Ferramolino offra molteplici spunti di interesse. La sua lunga attività professionale, documentata per almeno un trentennio, il suo amplissimo raggio d’azione – dai territori della Serenissima, alla Repubblica di Ragusa, alla Sicilia, da Malta ai presidi africani d’oltremare, la Goletta di Tunisi per prima –, certi accenti del suo carattere, tra cui quel fare spregiudicato che lo portò, anche grazie ad entrature a Corte, a mescolare al contempo responsabilità progettuale e intervento in qualità di impresario edile nei medesimi cantieri, sono tutti elementi che spingono, anche alla luce di nuove e corpose acquisizioni documentarie, verso un aggiornamento del suo profilo biografico e del quadro d’insieme della sua attività professionale, nell’ambito del quale si possa finalmente far luce sulle peculiarità del suo modus operandi e sulle innovazioni tecniche da lui introdotte nelle fortificazioni delle diverse sponde del Mediterraneo. Thirty years already went by since the publication of major monographic contributions by Guido Tadini on the complex and fascinating figure of Antonio Ferramolino from Bergamo, certainly one of the most distinguished military engineers at the service of the Spanish monarchy in the Mediterranean in the early sixteenth century. Although the most recent studies, particularly those on the engineer Pietro Antonio Tomasello from Padua, his predecessor, have partially reduced the "pioneering" role in the process of enhancement of Sicilian defenses that historiography had attributed to him, the figure of Ferramolino undoubtedly still presents many points of interest. His long professional activity, documented for at least three decades, with a very wide scope of action - from the Venetian territories, to the Republic of Ragusa and Sicily, from Malta to north African strongholds -, certain aspects of his character, including an unprejudiced behavior that led him to combine design responsibility and intervention as a building contractor in the same building site, are all elements to consider, especially in light of new documentary acquisitions, for an update of his biographical profile.

Abstract

Il disegno planimetrico adottato nelle cattedrali di età normanna, e in particolare nel duomo di Monreale, fino al principio dell’età moderna è un punto di riferimento nella progettazione di chiese di nuova costruzione in Sicilia. Non si tratta tuttavia di una inerziale ripetizione, ma di un riferimento non scevro di “riformulazioni”. Alcuni casi fanno registrare in particolare una variante nell’icnografia absidale, dove la sagoma semicircolare viene rimpiazzata da una pianta poligonale, relazionabile all’arrivo di soluzioni formali, tecniche e costruttive proprie della stagione gotica. L’esordio in Sicilia di una soluzione poligonale chiaramente concepita come alternativa all’icnografia semicircolare sembrerebbe riferibile alla fondazione delle basiliche francescane di Palermo e Messina, nella seconda metà del XIII secolo. Dopo questi episodici esordi, soluzioni poligonali trovano una più ampia affermazione a partire dal Trecento, con un successo duraturo almeno fino ai primi decenni del Cinquecento. Il saggio traccia un quadro delle diverse declinazioni del tema riscontrabili nell'architettura siciliana nell'ampio arco cronologico indicato, proponendo puntuali riflessioni su modelli di riferimento, vantaggi e motivazioni che stanno alla base di un scelta apparentemente solo formale, ma in realtà ricca di svariate implicazioni. La casistica presentata mostra come l’adozione del nuovo modello icnografico per le absidi associate agli impianti basilicali, tra XIV e XVI secolo, passi in Sicilia da un ripensamento dello stesso e una mediazione con i caratteri delle precedenti strutture absidali realizzate nell’isola. L’adozione dell’abside poligonale non si esaurisce in Sicilia con gli esempi presentati e nell’arco cronologico analizzato, ma prosegue nel corso del XVI secolo e talora oltre. Tuttavia, a partire dagli anni trenta del XVI secolo si registra parallelamente anche un ritorno all’abside semicircolare, tra le citazioni neo-normanne di un fenomeno di revival, che investe l’architettura siciliana nel secondo quarto del Cinquecento. The planimetric design adopted in Norman cathedrals and specifically in Monreale Cathedral served as a model in the design of new churches in Sicily untile the beginning of the modern period. However, it is not a matter of mere repetition but of a template that witnessed various "reformulations".Some casesshow a variation in apsidal iconography, where the semicircular shape is replaced by a polygonal plan probably linked to the arrival of formal, technical and construction solutions of the Gothic period. The debut in Sicily of a poligonal solution clearly concieved as an alternative to the semicircular iconography seems to be attributable to the construction of the Franciscan basilicas of Palermo and Messina, in the second half of the 13th century. After these episodic beginnings, polygonal solutions seemed to spread from the 14th century, with a success lasting at least until the early decades of the 16th century. The paper gives an overview of the various facets of the theme seen in the architecture of Sicily in the large time span indicated by offering precise reflections on reference models, benefits and reasons that underlie a choice apparently only formal, but in reality full of several implications.

Abstract

The finding at the National Library of Spain of an eighteenth-century engraving of the bridge over the river Milicia, along the coast to the east of Palermo, is a chance not only to shed light on the complex history of the design and construction of one of the main Sicilian bridges, but also to attribute the real paternity rather than to the famous architect Ferdinando Fuga to the lesser-known military engineer, serving the Austrian Crown, Michelangelo Blasco, whose long and successful career is reconstructed: from Sicily, through Milan, Wien and Lisbon, to the uncharted territory of Brazil.

Abstract

During the Sixteenth century and the first half of the following one, Sicily played a key role in the strategy of defense of the Spanish Empire from the looming Turkish threat, being an island considered as a baluarte against the Turks. Yet despite this absolute centrality in the military policy of the Spanish monarchy, till now historical research has preferred to provide broader spectrum interpretations at the expense of in-depth studies on individual technicians or overall pictures about the figure of the military engineer. We will present a synoptic view attesting the time period of activity covered by each military technician working for the kingdom of Sicily, within a wider study concerning the origin of this professional figure, the diversification of technicians working on fortifications, the progressive changes in the organizational chart and the enrichment of competences for military engineers much beyond l’arte del fortificare.

Abstract

Nei primi decenni del XII secolo si realizzano in Sicilia numerosi edifici religiosi, le cui absidi seguono in genere i modelli bizantini, ma non mancano soluzioni originali. Tra le chiese basiliane del Val Demone si distingue quella dei Santi Pietro e Paolo a Casalvecchio Siculo (1117-1172), la cui abside centrale assume esternamente la forma di una torretta a pianta rettangolare, che include due nicchie pentagonali negli spazi di raccordo con la curva interna. Tutte e tre le absidi della chiesa di Sant’Andrea a Piazza Armerina (ante 1148) presentano esternamente un profilo rettilineo e la massiccia struttura muraria ingloba la torre campanaria. Nella cappella palatina di Palermo, consacrata nel 1140, le tre conche sono unificate posteriormente da un volume poligonale, il cui riferimento più prossimo va ricercato nei modelli bizantini. L’analisi delle strutture murarie evidenzia che tale geometria viene fissata fin dalla realizzazione della primitiva cappella del palazzo (la cosiddetta cripta), su cui poggia la chiesa superiore. Lo sperimentalismo planimetrico che si rileva in questi esempi, forse favorito dalle ridotte dimensioni degli edifici, verrà in seguito abbandonato in favore di soluzioni più consuete, privilegiando nelle absidi delle grandi cattedrali gli aspetti prettamente decorativi. Between the last decades of the 11th century and the beginning of the next, after Sicily's return to Christi- anity after the long period of Islamic rule, the island witnessed the almost simultaneous outburst of new constructions of religious buildings. It was a time of experimentation in spatial patterns and new building solutions that blended together the different cultures present on the island, namely the Byzantine, Islamic and Norman civilizations. Due to their function and symbolic value, apses were always the focus of special attention, which in Nor- man churches was evident in the rich decoration of the facing walls, as opposed to the bare interior sur- faces, usually intended to accommodate mosaics or frescoes. Alongside the "canonical" solution of the three curved volumes – corresponding to the ritual spaces of the bema, prothesis and diaconicon – adopted in the apses of the early cathedrals (Troina, Catania and Mazara del Vallo), various other alternatives were ex- perimented. Among the Basilian churches, concentrated mainly in the mountainous areas of northeastern Sicily, the church of Santi Pietro e Paolo in Casalvecchio Siculo stands out for the originality of the apse. It is de- signed as an embattled tower with a rectangular plan built around the inner curve and the conch, forming two pentagonal niches at the base in the adjoining spaces. The Church was built around 1116, the year in which the Abbot Gerasimos received lands and other assets from Roger II, later King of Sicily, but it suffered serious damage as a result of the earthquake of 1169. It is no coincidence that two years later the building was renovated at the expense of the cate- chumen Theosterictus under the direction of the pro- tomagister Girard the Frank, whose name seems to indicate that he came from France.

Abstract

Sino a questo momento la realizzazione della strada Maqueda è stato oggetto quasi esclusivamente di interpretazioni critiche che ne hanno correttamente sottolineato la valenza simbolica, soprattutto con riferimento alla ostentazione di quella croce espressione di un cattolicesimo fattosi sempre più ortodosso e oltranzista; poco si è detto, invece, sugli aspetti legati ai processi di costruzione materiale di questo spazio urbano, alle operazioni correlate all’apertura per sventramento, nel tessuto denso e compatto di una delle principali città mediterranee, di una arteria stradale lunga quasi 1 chilometro e mezzo e larga oltre 11 metri, un rettifilo che all’anno 1600 costituiva nel panorama europeo un intervento urbanistico di grande arditezza. In questo contributo, anche grazie all’ausilio di nuova documentazione d’archivio, si proverà a far luce sui protagonisti di questa impresa architettonica, su fasi, tempi e modalità di organizzazione del cantiere, nonché su strumenti e tecniche impiegate per il controllo dello spazio urbano al fine del corretto tracciamento del nuovo asse stradale sul costruito. Till now the project of strada Maqueda has been subjected almost exclusively to critical interpretations that have properly emphasized its symbolic value, especially with reference to the showing, at an unprecedented urban scale, of the symbol of the cross, expression of a Catholicism increasingly orthodox and extremist; little has been said, on the other hand, on issues related to the process of material construction of this urban space, to the operations and procedures related to the opening by disembowelment, in the dense and compact structure of one of the main Mediterranean capitals, of a road long almost one kilometer and a half, and large more than 11 meters, a rettifilo that in the year 1600 represented on the European scene an extremely complex urban intervention. In this contribution, even with the aid of new archival documentation, I will try to shed light on the protagonists of this architectural achievement, on steps, timing and mode of organization of the construction site, as well as tools and techniques used to control the urban space in order to track properly the new road through the medieval neighborhoods.

Abstract

In Sicilia, nell’Ottocento, si assistette in architettura a un revival neonormanno che trovava in quel momento glorioso della storia isolana la legittimazione per rivendicazioni autonomiste mirate alla ricostituzione di un regno di Sicilia finalmente libero dal giogo borbonico e da Napoli. Tuttavia, un fenomeno culturale analogo si era già registrato nel corso del xvi secolo. Nel rinascimento siciliano, infatti, si guardò non soltanto al classicismo e alla Roma dei Cesari, ma anche all’eredità del medioevo normanno, nel tentativo forse di costruire un’identità per un’isola, come la Sicilia asburgica, non libera e melting pot di culture diverse. Il caso del mito normanno presenta, però, in sé una sorprendente contraddizione: da un lato questo supporta la costruzione di un’identità «nazionale» siciliana, dall’altro diviene strumento formidabile per la corona spagnola, ugualmente in prima linea contro il nemico musulmano, di corroborazione del potere monarchico e di controllo dell’isola, During the 19th century Sicilian architecture saw a return to a neo-Norman style, with that glorious moment in the island’s history offering legitimation to the calls for autonomous rule that envisaged the recovery of the kingdom of Sicily and freedom from the Bourbonic yoke and subordination to Naples. However, a similar phenomenon had already occurred during the 16th century. The Sicilian Renaissance drew inspiration not only from classicism, but also from the legacy of its Norman Middle Ages, perhaps in an attempt to build an identity for the island, like Habsburgs’ Sicily, rather than let it be free and a melting pot of cultures. But the Norman myth shows a surprising contradiction: on one hand it lent support to the construction of a Sicilian “national” identity, on the other it became a powerful tool for the Spanish Crown to strengthen its monarchical power and its control on the island

Abstract

Il saggio, attraverso l’individuazione e l’interpretazione di una copiosa documentazione archivistica, prova a formulare una ipotesi sulla possibile configurazione del campanile della chiesa Madre di Caltagirone ai primi decenni del Seicento e in particolare a seguito dell’intervento di consolidamento (ma forse anche di ammodernamento), condotto dallo scultore-architetto Giovan Domenico Gagini, in concomitanza del cantiere da questi diretto per l’ampliamento della chiesa madre calatina. Vengono così avanzate proposte riguardo ai possibili modelli compositivi e linguistici adottati, tra questi in primo luogo quelli offerti dai Libri di Sebastiano Serlio, provando al contempo a ricostruire il complesso intreccio di progetti, cantieri e protagonisti, tanto tecnici quanto committenti, che sembra saldare fra loro i centri principali dell’intero Val di Noto fra XVI e XVII secolo: Siracusa, Piazza Armerina, Noto, Caltagirone.

Abstract

International audience; The knowledge of initial flux, energy and flavor of neutrino beams is currently the main limitation for a precise measurement of neutrino cross sections. The ENUBET project is studying a facility based on a narrow band neutrino beam capable of constraining the neutrino fluxes normalization through the monitoring of the associated charged leptons in an instrumented decay tunnel. In particular, the identification of large-angle positrons from $K_{e3}$ decays at single particle level can potentially reduce the $\nu_{e}$ flux uncertainty at the level of 1%.The ENUBET Collaboration presented at EPS-HEP2019 the advances in the design and simulation of the hadron beam line, the performance of positron tagger prototypes tested at CERN beamlines, a full simulation of the positron reconstruction chain and the expected physics reach.

Abstract

L’uso di modelli digitali per lo studio e la prefigurazione dell’architettura è divenuta negli ultimi venti anni una prassi che può ritenersi consolidata; i modelli digitali hanno aperto nuove prospettive di ricerca anche all’indagine storica, specie se condotta su manufatti diruti. In alcuni casi il modello digitale costituisce una soluzione efficace per la prefigurazione di progetti mai realizzati o per l’anastilosi virtuale di edifici perduti; la validità scientifica di tali modelli è strettamente legata alla coerenza delle metodologie di ricostruzione adottate, ad un sistematico ricorso alle fonti documentarie e alla validazione di precedenti ipotesi ricostruttive. Il presente contributo propone due ipotesi ricostruttive sul Castellammare di Palermo, monumento di cui rimangono solo pochi ruderi a causa delle demolizioni eseguite nel 1922. Le due ricostruzioni, fondate sull’analisi delle fonti iconografiche e archivistiche, conducono alla formulazione di nuove ipotesi sulle vicende costruttive della fabbrica, tuttora poco note.
