Abstract: CUORE is a tonne-scale cryogenic experiment located at the Laboratori Nazionali del Gran Sasso that exploits bolometric technique to search for neutrinoless double beta decay of 130Te. Thanks to its very low background and large mass, CUORE is also a powerful tool to study a broad class of phenomena, such as solar axions and WIMP scattering. The ability to conduct such sensitive searches crucially depends on the energy threshold, which has to be kept as low as possible. In this contribution, we show how the trigger algorithm affects the sensitivity to low-energy phenomena and the interpretation of the energy spectrum. In particular, we focus on the impact that the trigger algorithm has on the identification of the coincidence events among different crystals and, consequently, on the reconstruction of the background.

Abstract: The Cryogenic Underground Observatory for Rare Events (CUORE) is the most massive bolometric experiment searching for neutrino-less double beta (0 ν β β ) decay. The detector consists of an array of 988 TeO 2 crystals (742 kg) arranged in a compact cylindrical structure of 19 towers. This paper will describe the CUORE experiment, including the cryostat, and present the detector performance during the first year of running. Additional detail will describe the effort made in improving the energy resolution in the 130Te 0 ν β β decay region of interest (ROI) and the suppression of backgrounds. A description of work to lower the energy threshold in order to give CUORE the sensitivity to search for other rare events, such as dark matter, will also be provided.

Abstract: The Cryogenic Underground Observatory for Rare Events (CUORE) is the first bolometric experiment searching for neutrinoless double beta decay that has been able to reach the 1-ton scale. The detector consists of an array of 988 TeO 2 crystals arranged in a cylindrical compact structure of 19 towers, each of them made of 52 crystals. The construction of the experiment was completed in August 2016 and the data taking started in spring 2017 after a period of commissioning and tests. In this work we present the neutrinoless double beta decay results of CUORE from examining a total TeO 2 exposure of 86.3 kg yr , characterized by an effective energy resolution of 7.7 keV FWHM and a background in the region of interest of 0.014 counts / ( keV kg yr ) . In this physics run, CUORE placed a lower limit on the decay half-life of neutrinoless double beta decay of 130 Te &gt, 1.3 &middot, 10 25 yr (90% C.L.). Moreover, an analysis of the background of the experiment is presented as well as the measurement of the 130 Te 2 &nu, &beta, decay with a resulting half-life of T 1 / 2 2 &nu, = [ 7.9 &plusmn, 0.1 ( stat . ) &plusmn, 0.2 ( syst . ) ] &times, 10 20 yr which is the most precise measurement of the half-life and compatible with previous results.

Abstract: International audience; CUORE is the first bolometric tonne-scale experiment aiming at the investigation of neutrinoless double-beta (0$\nu$2$\beta$) decay of $^{130}$Te. The cryogenic commissioning followed by the detector installation and cool down took place during 2016. After the optimisation of all the detectors, the data-taking started in spring 2017. We report about the results of the first dataset acquired in May, which led to a limit on the 0$\nu$2$\beta$ half-life of $^{130}$Te of 6.6$\times$10$^{24}$ yr. An upgrade of CUORE, named CUPID, is planned to improve the 0$\nu$2$\beta$-decay sensitivity via passive and active background reduction and crystal enrichment. Some technologies for CUPID are currently under study and two of them are presented here, involving the detection of Cherenkov and scintillation light emitted by enriched $^{130}$TeO$_2$ and Li$^{100}_2$MoO$_4$ crystals respectively. This will allow us to reject the currently dominant a background.

Abstract: CUORE, the Cryogenic Underground Observatory for Rare Events, is an experiment searching for the neutrinoless double-beta decay of 130Te. The first CUORE dataset was acquired in May and June 2017 and consisted of 10.6 kg-yr of TeO2 exposure, with several days of calibration data before and after the physics dataset. We discuss here the initial performance of the CUORE detector and cryostat in this first dataset.

Abstract: International audience; The Cryogenic Underground Observatory for Rare Events (CUORE) is an upcoming experiment designed to search for the neutrinoless double-beta decays. Observation of the process would unambiguously establish that neutrinos are Majorana particles and provide information on their absolute mass scale hierarchy. CUORE is now under construction and will consist of an array of 988 TeO2 crystal bolometers operated at 10 mK, but the first tower (CUORE-0) is already taking data. The experimental techniques used will be presented as well as the preliminary CUORE-0 results. The current status of the full-mass experiment and its expected sensitivity will then be discussed.

Abstract: International audience; The CUORE-0 experiment, a 52 bolometer array searching for neutrinoless double beta decay from 130Te, has started taking data in spring 2013 underground at the Laboratori Nazionali del Gran Sasso (LNGS). The excellent results obtained in terms of energy resolution and background level allowed this experiment to reach the sensitivity of Cuoricino in approximately half the runtime. Combining CUORE-0 data (9.8 kg·yr exposure of 130Te) with the 19.75 kg·yr exposure of the Cuoricino experiment, we obtain the most stringent limit to date on the half-life of this isotope (T1/2 > 4.0 × 1024 yr). In this article, we review the results from CUORE-0 and discuss the status and the physics potential of CUORE, a 19 times larger bolometer array that plans to begin operations by end of this year.

Abstract: The Cryogenic Underground Observatory for Rare Events (CUORE) is an experiment to search for neutrinoless double beta decay ($0\nu\beta\beta$) in $^{130}$Te and other rare processes. CUORE is a cryogenic detector composed of 988 TeO$_2$ bolometers for a total mass of about 741 kg. The detector is being constructed at the Laboratori Nazionali del Gran Sasso, Italy, where it will start taking data in 2015. If the target background of 0.01 counts/(keV$\cdot$kg$\cdot$y) will be reached, in five years of data taking CUORE will have an half life sensitivity around $1\times 10^{26}$ y at 90\% C.L. As a first step towards CUORE a smaller experiment CUORE-0, constructed to test and demonstrate the performances expected for CUORE, has been assembled and is running. The detector is a single tower of 52 CUORE-like bolometers that started taking data in spring 2013. The status and perspectives of CUORE will be discussed, and the first CUORE-0 data will be presented., Comment: Proceedings of a talk given at the International Conference of New Frontiers in Physics, ICNFP 2014; submitted at EPJ Web of Conferences

Abstract: CUORE-0 is an experiment built to test and demonstrate the performance of the upcoming CUORE experiment. Com- posed of 52 TeO2 bolometers of 750g each, it is expected to reach a sensitivity to the 0νββ half-life of 130Te around 3 · 1024 y in one year of live time. We present the first data, corresponding to an exposure of 7.1kg y. An analysis of the background indicates that the CUORE sensitivity goal is within reach, validating our techniques to reduce the α radioactivity of the detector.

Abstract: The Cryogenic Underground Observatory for Rare Events (CUORE) is a ton-scale experiment made of TeO2 bolometers that will probe the neutrinoless double beta decay of 130Te. Excellent energy resolution, low threshold and low background make CUORE sensitive to nuclear recoils, allowing a search for dark matter interactions. With a total mass of 741 kg of TeO2, CUORE can search for an annual modulation of the counting rate at low energies. We present data obtained with CUORE-like detectors and the prospects for a dark matter search in CUORE-0, a 40-kg prototype, and CUORE.

Abstract: The CUORE (Cryogenic Underground Observatory for Rare Events) experiment will search for neutrinoless double beta decay in {Mathematical expression}Te. Observation of the process would unambiguously establish that neutrinos are Majorana particles as well as provide information about the absolute neutrino mass scale and mass hierarchy.The CUORE setup will consist of an array of 988 tellurium dioxide crystals (containing 206 kg of {Mathematical expression}Te in total), operated as bolometers at a temperature of {Mathematical expression}10 mK. The experiment is now under construction at the Gran Sasso National Laboratory in Italy. As a first step towards CUORE, a tower (CUORE-0) has been assembled and is taking data. Here a detailed description of the CUORE-0 tower and its performance is reported. The status of the CUORE experiment and its expected sensitivity will then be discussed. © 2014 Springer Science+Business Media New York.

Abstract: Neutrinoless double beta decay (0nubb) is one of the most sensitive probes for physics beyond the Standard Model, providing unique information on the nature of neutrinos. In this paper we review the status and outlook for bolometric 0nubb decay searches. We summarize recent advances in background suppression demonstrated using bolometers with simultaneous readout of heat and light signals. We simulate several configurations of a future CUORE-like bolometer array which would utilize these improvements and present the sensitivity reach of a hypothetical next-generation bolometric 0nubb experiment. We demonstrate that a bolometric experiment with the isotope mass of about 1 ton is capable of reaching the sensitivity to the effective Majorana neutrino mass (|mee|) of order 10-20 meV, thus completely exploring the so-called inverted neutrino mass hierarchy region. We highlight the main challenges and identify priorities for an R&D program addressing them., 22 pages, 15 figures, submitted to EPJC

Abstract: Since many years the Milano Gran Sasso collaboration is developing large mass calorimeters for Double Beta Decay and Dark Matter searches, employing TeO2 crystals as absorber elements. Recently, we have focused our attention on the improvement of the detector resolution: an efficient dumping suspension and the implementation of a new cold electronics device, have strongly suppressed the main sources of noise. The increase in SIN ratio has been of almost an order of magnitude and the resolution achieved is competitive with that of Ge diodes for gamma -rays detection, while a FWHM of 3.2 +/-0.3 keV has been obtained for 5.4 MeV alpha particles, the best result with any kind of detector.

Abstract: Massive low temperature particle detectors and their possible impacts on searches for neutrinoless double beta decay (Oν-DBD) are presented and discussed. In particular, the experimental work of the Milano group is described. Special relevance is given to the present status of the search for Oν-DBD of 130Te and to the possible expansion of this experiment in the near future. The most recent results obtained by the Milano-Gran Sasso collaboration with a 20 bolometer array are presented. On the basis of these results, the construction of a 42 kg array consisting of 56 TeO2 bolometers (CUORICINO project), to extend the sensitivity of the present experiment, has been proposed. CUORICINO should represent also a feasibility test for a large array of 1000 bolometers (CUORE project) aiming at the search for neutrinoless Double Beta Decay, Cold Dark Matter and Solar Axions with extremely high sensitivity.

Abstract: The low-Q 187Re forbidden beta transition is studied by means of a microbolometers array in order to get a direct limit on the νe mass. The achievable limit of the on-the-shelf small array (ten detectors) in one year measure acquisition time is less than 10eV/c2. Silicon and Germanium thermistors are being developed also for high resolution x-ray spectroscopy; an excellent energy resolution of 5.4eV in the 6keV region has been achieved. This represent the best published result of an Energy Dispersive Sensor (EDS) in this spectral band.

Abstract: Present results on neutrinoless double beta decay of 130Te obtained with an array of 20 cryogenic detectors are presented. The setup consists of 20 crystals of tellurium oxide of 340 g each, corresponding to the largest presently operating cryogenic mass. Combining the results of the few runs obtained with the same array, corresponding to 1.5 kg yr, a limit on neutrinoless double beta decay half-life of 9.5]1022 yr (90% CL) has been obtained. On the basis of the results obtained with the MI-BETA experiment, we propose a construction of a 42 kg array of 56 TeO 2 bolometers (CUORICINO project) to extend the sensitivity of the present experiment, and as a "rst test for CUORE. Thanks to an innovative technique of vibration reduction and despite the high mass (750 g instead of the 340 g of the presently running detectors) we reached an energy resolution of 3.9 keV FWHM at 2615 keV decreasing to 1.4 keV at low energies.

Abstract: In this paper we present the excellent results obtained by mechanical decoupling of our thermal detectors from the cryostat. The starting point of this work is the necessity to improve the performances of thermal detectors and, besides, to eliminate the non-constant noise resulting from the overall cryogenic facility; this second point results to be crucial for rare-events experiments and the fundamental task for Dark Matter search. Tested on our bolometer, consisting of a 750 g tellurium oxide absorber coupled with an NTD thermistor and operated at &9 mK in an Oxford 200 dilution refrigerator, this powerful technique can, moreover, provide advantages for a large variety of thermal detectors. A good energy resolution of 3.9 keV FWHM was obtained for 2.615 MeV c-rays. The 4.2 keV average FWHM resolution for the 5407 keV 210Po a decay line is the best ever obtained for a-particles with any type of detector. ( 2000 Elsevier Science B.V. All rights reserved.

Abstract: In this paper we want to discuss the results obtained on bolometer detectors in the last year by the Milano Group. At first we will show the results on double decay of 130 Te obtained running an array of twenty cryogenic detectors for about 1450h (0.31Kg/y of 130 Te under test). The set-up is made with crystals of TeO 2 of 340 grams each. It was run in the Gran Sasso Underground Laboratory at a depth of about 3500 m.w.e. By recording the pulses of each detector, in anticoincidence with the others, a 90% c.l. lower limit of 0.87×10 23 years has been obtained on neutrinoless ββ decay of 130 Te. Then we will show the exceptional energy resolution of two bolometers composed of tin absorbers and NTD Ge thermistors. They have been fabricated in preparation of experiments in nuclear and subnuclear physics. Both detectors fully resolve the two K α1 and K α2 lines of 55 Mn. The deconvolved FWHM resolution in this energy region ranges from 4.5 to 5.7 eV, according to different intrinsic measured value of those lines.

Abstract: We collected 19.4 days of data from four 750 g TeO2 bolometers, and in three of them we were able to set the energy threshold around 3 keV using a new analysis technique. We found a background rate ranging from 25 cpd/keV/kg at 3 keV to 2 cpd/keV/kg at 25 keV, and a peak at 4.7 keV. The origin of this peak is presently unknown, but its presence is confirmed by a reanalysis of 62.7 kg.days of data from the finished CUORICINO experiment. Finally, we report the expected sensitivities of the CUORE0 (52 bolometers) and CUORE (988 bolometers) experiments to a WIMP annual modulation signal., 9 pages, 10 figures

Abstract: At the end of 2001 the Milano Double Beta Decay (MI-DBD) experiment on double beta decay of 130Te has been completed. The project Cryogenic Underground Observatory for Rare Events (CUORE), proposed as a natural extension of MI-DBD, will be a tightly packed array of 1000 TeO2 bolometers, each being a cube 5 cm on a side with a mass of 790 g. The array will consists of 25 vertical towers, arranged in a square of 5 towers by 5 towers, each containing 10 layers of 4 crystals. A single CUORE tower has been constructed as a smaller scale experiment called CUORICINO. The technical feasibility of CUORE is now being tested in CUORICINO, running since few weeks. The CUORICINO experiment consists of 44 TeO2 detectors 5×5×5 cm3 and 18 TeO2 detectors 3×3×6 cm3 for a total mass of approximately 41 kg. An analysis of the detector performances is presented together with the new limit obtained on neutrinoless double beta decay of 130Te.

Abstract: Germanium wafers exposed to intense neutron beams from a nuclear reactor to produce neutron transmutation doped thermistors have been analysed for residual radioactivity in view of their application in experiments on rare decays. Measurements have been routinely carried out for more than three years with germanium spectrometers of low intrinsic radioactivity operating in the Gran Sasso Underground Laboratory in order to suppress the background due to cosmic rays. Four long lived nuclei produced during the irradiation by the fast neutron component of the flux have been identified. It is shown that two of them will contribute considerably to the background in experiments on rare events carried out with thermal detectors, especially in the direct search of dark matter. These measurements also enable investigation of the presence of contaminants in the germanium wafer before irradiation. The sensitivity can be as low as 10−14 g g for some elements.

Abstract: We present a search for β+/EC double beta decay of 120Te performed with the CUORICINO experiment, an array of TeO2 cryogenic bolometers. After collecting 0.0573 kg · y of 120Te, we see no evidence of a signal and therefore set the following limits on the half-life: T1/20ν>1.9·1021 y at 90% C.L. for the 0ν mode and T1/22ν>7.6·1019 y at 90% C.L. for the 2ν mode. These results improve the existing limits by almost three orders of magnitude (four in the case of 0ν mode). © 2011 Published by Elsevier B.V.

Abstract: CdWO4 bolometers were realized with the final purpose to study Double Beta Decay of116Cd. The test device we developed performs as a very efficient γ detector, with a preliminary resolution of aboout 5 keV FWHM. The detector background spectra are dominated at low energies by β decay of113Cd: the calorimetric measurement of this process allows to detrmine the end point (318.8±1.4±5 keV) and with unprecedented precision the life time ((9,3±0.5±1)×1015 y). Following the same approach, we have analysed the internal contamination in210Pb of three different types of lead used for shielding in low background experiments. Various lead bolometers were developed and operated, using common modern lead, special low activity modern lead and 2000 years old Roman lead. The presence of210Pb was clearly observed through the α decay of its daughter210Po in the modern samples, while only a limit was set for the much purer Roman lead. The purifying effect of crystallization was clearly demontrated.

Abstract: Low temperature bolometers can be complementary and sometimes superior to “classical” ionization detectors in many experiments without accelerators in nuclear, subnuclear and astroparticle physics. After a short review of the “tools” that cryogenics offer for the detection of particles we first consider a few practical applications of bolometers in the spectroscopy of α, γ and X rays, in the detection of neutrons and in measurements of weak radioactive contaminations. Searches with this tecnique on single and double beta decay, of which some are already being carried out, are then considered and discussed. The various properties which make thermal detectors particularly suitable for searches on dark matter are reviewed, stressing the potentiality of this technique. The promising, but still far, potentiality of thermal detectors in solar neutrino experiments is finally discussed.

Abstract: A 73.1 g TeO 2 bolometric detector has been operating for more than 4 months at about 16 mK in the Gran Sasso Underground Laboratory. Its energy resolution is comparable with that of a Ge diode. We performed two measurements: without (1389 hours of effective running time) and with (1046 hours) an inner ultra-low activity lead shield of about 3.5 cm in every direction. The energy spectra of thermal pulses show no evidence for 0-ν ββ decay of 130 Te. The corresponding 90% c.l. lower limit on the half-life time, 2.7×10 21 y, exceeds the value, quoted by geochemical measurements, for the inclusive (2-ν plus 0-ν decay channels) half-life time: 8×10 20 y [1] . Therefore ββ decay of 130 Te has to be attributed mainly to the 2-ν channel.

Abstract: A thermal detector consisting of a 34 g TeO2 crystal has been operated at about 20 mK in a specially constructed low activity dilution refrigerator installed in the Gran Sasso Underground Laboratory. A spectrum of the thermal pulses collected in more than thousand hours of effective running time shows no evidence for neutrinoless double beta decay of 130Te. The corresponding lower limit on the process lifetime is two orders of magnitude more stringent than those obtained for the same nucleus with counter techniques and of the same order as the values yielded by geochemical searches.

Abstract: Our group is involved in experiments using bolometric detectors since ten years for rare event searches like double beta decay or Dark Matter interactions. During last year, to check the quenching factor of TeO 2 bolometers, we have measured the nuclear recoils at energy as low as 15 keV in our experimental apparatus at Laboratori Nazionali del Gran Sasso. Two 72g TeO 2 detectors were exposed under vacuum to a 228Ra a source that implanted on them 224Ra nuclei. The nuclei emitted by the implanted source were detected in one bolometer in coincidence with the corresponding a particles in the other. The energy spectrum of the 103.4 keV 224Ra nuclei has been obtained with an energy resolution of about 12 keV. Furthermore an a measurement of Roman lead has exploited also the sensitivity of this technique to check for ultralow activity in matter, taking advantage of the source,detector approach. A limit on the 210Pb contamination in roman lead as low as 4 mBq/Kg has been obtained. ( 1998 Elsevier Science B.V. All rights reserved.

Abstract: CUORICINO is an array of 62 TeO2 bolometers with a total mass of 40.7 kg (11.2 kg of 130Te), operated at about 10 mK to search for ββ(0ν) of 130Te. The detectors are organized as a 14-story tower and intended as a slightly modified version of one of the 19 towers of the CUORE project, a proposed tightly packed array of 988 TeO2 bolometers (741 kg of total mass of TeO2) for ultralow-background searches on neutrinoless double-beta decay, cold dark matter, solar axions, and rare nuclear decays. Started in April 2003 at the Laboratori Nazionali del Gran Sasso (LNGS), CUORICINO data taking was stopped in November 2003 to repair the readout wiring system of the 62 bolometers. Restarted in spring 2004, CUORICINO is presently the most sensitive running experiment on neutrinoless double-beta decay. No evidence for ββ(0ν) decay has been found so far and a new lower limit, T 1 2/0 ≥ 1.8 × 1024 yr (90% C.L.), is set, corresponding to 〈m ν〉 ≤ 0.2–1.1 eV, depending on the theoretical nuclear matrix elements used in the analysis. Detector performance, operational procedures, and background analysis results are reviewed. The expected performance and sensitivity of CUORE is also discussed.

Abstract: CUORE (Cryogenic Underground Observatory for Rare Events) is an experiment proposed to infer the effective Majorana mass of the electron neutrino from measurements on neutrinoless double beta decay (0νDBD). The goal of CUORE is to achieve a background rate in the range 0.001 to 0.01 counts/keV/kg/y at the 0νDBD transition energy of 130Te (2528 keV). The proposed experiment, to be mounted in the underground Gran Sasso INFN National Laboratory, Italy, is realized by cooling about 1000 TeO2 bolometers, of 750 g each, at a temperature of 10mK. We will describe the experiment, to be cooled by an extremely powerful dilution refrigerator, operating with no liquid helium, and the main experimental features designed to assure the predicted sensitivity. We present moreover the last results of a small scale (40.7 kg) 0νDBD experiment carried on in the Gran Sasso Laboratory (CUORICINO).

Abstract: Preliminary results on double beta decay (DBD) of 130Te, obtained in the first run of the CUORICINO experiment are presented. The set-up consists of an array of 62 crystals of TeO2 operating as bolometers in a deep underground dilution unit at a temperature of about 10 mK. Due to a total mass of about 41 kg, CUORICINO represents by far the most massive running cryogenic mass to search for rare events. The achieved lower limit on the neutrinoless DBD is 5.5·1023 years, that corresponds to a limit on the Majorana effective mass between 0.37 and 1.9 eV. Performances of the detectors together with the sensitivity estimation are discussed. © 2004 Elsevier B.V. All rights reserved.

Abstract: Improvements in cryogenic thermal detector performances have triggered new generation experiments based on this devices. MiBeta detector had shown, during the last five years, the potential of a large mass cryogenic detector for long running time, good energy resolution, low energy threshold and low radioactive background experiment. Starting from this point a new very large cryogenic detector was proposed: CUORE (Cryogenic Underground Observatory for Rare Events). CUORE will be a segmented detector made with 1000 crystals of TeO2 of 5×5×5 cm3, for a total detector mass around 760 kg. Thanks to the high granularity a considerable improvement in background rejection can be reached using coincidence analysis between crystals. The main goal of CUORE will be the search of neutrinoless double beta decay of 130Te but also other studies are possible; in particular dark matter and solar axion searches. To prove the feasibility of CUORE a pilot experiment named CUORICINO was proposed and also founded. The estimated sensitivities of CUORICDMO and CUORE for WIMPs searches is here reported.

Abstract: CUORE is a proposed tightly packed array of 1000 TeO2 bolometers, each being a cube 5 cm on a side with a mass of 760 g. The array consists of 25 vertical towers, arranged in a square of 5 towers by 5 towers, each containing 10 layers of 4 crystals. The design of the detector is optimized for ultralow-background searches: for neutrinoless double beta decay of 130Te (33.8% abundance), cold dark matter, solar axions, and rare nuclear decays. A preliminary experiment involving 20 crystals 3x3x6 cm3 of 340 g has been completed, and a single CUORE tower is being constructed as a smaller scale experiment called CUORICINO.

We present the analysis of the data collected during the first measurement with an array of AgReO4 crystals. The total mass and measuring time are about 2.3 mg and 10830 h x det respectively, giving a total statistics of approximately 6 x 10(6) (187R)e beta decays. We also report the preliminary results of a new measurement aiming at understanding the radioactive background observed in the previous data.

Abstract: High-Z low-temperature calorimeters are developed by an Italian collaboration (Milano-Como-Gran Sasso Underground Laboratories) in order to search for rare nuclear events and Dark Matter massive candidates. They exhibit an excellent energy resolution, close to that of Ge-diodes, but a much higher efficiency. Different high-Z materials were initially employed . A many-years optimisation work on tellurium oxide (TeO2) lead to impressive results: devices with total masses around 750 g present FWHM energy resolutions on gamma-ray peaks ranging from 1 KeV (close to the 5 KeV energy threshold) to 2.6 KeV at 2615 KeV (208Tl gamma line). A 3.2 KeV FWHM energy resolution was obtained at 5.4 MeV (210Po alpha line), which is by far the best one ever achieved with any alpha detector. These devices, operated at about 10 mK, consist of a TeO2 single crystal thermally coupled to a 50 mg Neutron Transmutation Doped (NTD) Ge crystal working as a temperature sensor. Special care was devoted to methods for response linearization and temporal stabilisation. Devices based on the same principle and specifically optimised could find applications in several fields like gamma-ray astrophysics, nuclear physics searches, environmental monitoring and radiation metrology.© (2001) COPYRIGHT SPIE--The International Society for Optical Engineering.

Abstract: During a Double Beta Decay experiment performed at Laboratori Nazionali del Gran Sasso, a 274 hours low-threshold background spectra was collected with a 340 g TeO2 detector. The MIBETA experiment consists of 20 Tellurium oxide crystals working as bolometers at T = 10 mK in a dilution refrigerator. We present here the analysis carried out on a single detector to search for possible WIMP signal. The values of parameters which are essential in the search for WIMP's, like energy resolution (similar to 2 keV), energy threshold (10 keV) and nuclear quenching factor (similar or equal to 1) have been experimentally determined and are discussed in detail. The exclusion plot of the spin-independent cross section of WIMP's on the nuclei is reported.

Abstract: We are presenting our recent developments to measure the electron antineutrino mass by studying the 187Re (beta) - spectrum end-point with high resolution thermal detectors. We will discuss the preliminary results of an array of 8 bolometers made up of AgReO4 absorbers (2.309 mg of total mass corresponding to a total 187Re active mass of about 0.905 mg of with an expected (beta) total rate of about 1.3 Hz). Their risetime of 0.7 - 1.2 ms together with their energy resolution, ranging between 21 eV and 26 eV at 1.5 KeV, should allow to set a limit of about 10 - 12 eV after one year of real time measurements.© (2000) COPYRIGHT SPIE--The International Society for Optical Engineering.

Abstract: A massive bolometer with a 760 g TeO2 crystal as energy absorber, the largest employed underground, has been realized and operated in the Gran Sasso Underground Laboratory for γ- and α-ray spectroscopy. A new system of mechanical suspensions was implemented to reduce vibration and thermal noise, and special care was put to the read-out electronics. As a consequence the FWHM resolution for high-energy γ-rays became comparable to that of Germanium diodes. The 4.2 keV average FWHM resolution for the 5407 keV line is the best ever obtained for α particles with any type of detector.

50. New experimental results on Double Beta Decay of 130Te

Abstract: New results are presented of a search for double beta decay of Te isotopes carried out, using the bolometric technique, with an array of 20 natural tellurite crystals with a total cryogenic mass of ; 6.8 kilograms. The array has been run at a temperature around 10 mK in the Gran Sasso Underground Laboratory. No evidence has been found for neutrinoless double beta decay of 128 Te and 130 Te and upper limits of 8.6 = 10 22 and 1.44 = 10 23 years, respectively, have been achieved at the 90% confidence level. From the latter we obtain limits on the lepton non-conserving parameters which are the most restrictive ones in direct experiments after those on 76 Ge according to theoretical calculations. Results on two neutrino and majoron mediated decays are also presented and discussed with respect to those obtained for the same nuclei in geochemical experiments. q 2000 Elsevier Science B.V.
