The sixth edition of the African School of Fundamental and Applied Physics (ASP) was planned for Morocco in July 2020 and was referred to as ASP2020. Preparations were at an advanced stage when ASP2020 was postponed because of the COVID-19 pandemic. The three-week event was restructured into two activities in 2021 -- an online event on July 19-30, 2021 and a hybrid event on December 12-18, 2021 -- and was renamed ASP2021. At the beginning of the COVID-19 pandemic, an online lecture series was integrated into the ASP activities. The ASP mentorship program, which consists of online engagements between lecturers and assigned mentees, continued in this way. ASP alumni studied one year of COVID-19 data of ten African countries to offer insights into pandemic containment measures. In this note, we report on ASP activities since the last in-person edition of ASP in 2018 in Namibia., Comment: 15 pages, 9 figures and 1 table

- Abstract
Detectors based on Chemical Vapor Deposition (CVD) diamond have been used successfully in Luminosity and Beam Condition Monitors (BCM) in the highest radiation areas of the LHC. Future experiments at CERN will accumulate an order of magnitude larger fluence. As a result, an enormous effort is underway to identify detector materials that can operate under fluences of 1 · 1016 n cm−2 and 1 · 1017 n cm−2. Diamond is one candidate due to its large displacement energy that enhances its radiation tolerance. Over the last 30 years the RD42 collaboration has constructed diamond detectors in CVD diamond with a planar geometry and with a 3D geometry to extend the material's radiation tolerance. The 3D cells in these detectors have a size of 50 µm×50 µm with columns of 2.6 µm in diameter and 100 µm×150 µm with columns of 4.6 µm in diameter. Here we present the latest beam test results from planar and 3D diamond pixel detectors., PoS: Proceedings of Science, 420, ISSN:1824-8039, 10th International Workshop on Semiconductor Pixel Detectors for Particles and Imaging

We measured the radiation tolerance of commercially available diamonds grown by the Chemical Vapor Deposition process by measuring the charge created by a 120 GeV hadron beam in a 50 µm pitch strip detector fabricated on each diamond sample before and after irradiation. We irradiated one group of samples with 70 MeV protons, a second group of samples with fast reactor neutrons (defined as energy greater than 0.1 MeV), and a third group of samples with 200 MeV pions, in steps, to (8.8 ± 0.9) × 1015 protons/cm2, (1.43 ± 0.14) × 1016 neutrons/cm2, and (6.5 ± 1.4) × 1014 pions/cm2, respectively. By observing the charge induced due to the separation of electron–hole pairs created by the passage of the hadron beam through each sample, on an event-by-event basis, as a function of irradiation fluence, we conclude all datasets can be described by a first-order damage equation and independently calculate the damage constant for 70 MeV protons, fast reactor neutrons, and 200 MeV pions. We find the damage constant for diamond irradiated with 70 MeV protons to be 1.62 ± 0.07 (stat) ± 0.16 (syst) × 10−18 cm2 /(p µm), the damage constant for diamond irradiated with fast reactor neutrons to be 2.65 ± 0.13 (stat) ± 0.18 (syst) × 10−18 cm2 /(n µm), and the damage constant for diamond irradiated with 200 MeV pions to be 2.0 ± 0.2 (stat) ± 0.5 (syst) × 10−18 cm2 /(π µm). The damage constants from this measurement were analyzed together with our previously published 24 GeV proton irradiation and 800 MeV proton irradiation damage constant data to derive the first comprehensive set of relative damage constants for Chemical Vapor Deposition diamond. We find 70 MeV protons are 2.60 ± 0.29 times more damaging than 24 GeV protons, fast reactor neutrons are 4.3 ± 0.4 times more damaging than 24 GeV protons, and 200 MeV pions are 3.2 ± 0.8 more damaging than 24 GeV protons. We also observe the measured data can be described by a universal damage curve for all proton, neutron, and pion irradiations we performed of Chemical Vapor Deposition diamond. Finally, we confirm the spatial uniformity of the collected charge increases with fluence for polycrystalline Chemical Vapor Deposition diamond, and this effect can also be described by a universal curve. © 2020 by the authors.

Physics::Instrumentation and Detectors ,Physics::Accelerator Physics ,Accelerators and Storage Rings - Abstract
Diamond detectors are used as beam loss and luminos- ity monitors for CMS and LHC. A time resolution in the nanosecond range allows to detect beam losses and lumi- nosities of single bunches. The radiation hardness and neg- ligible temperature dependence allow the usage of diamond sensors in high radiation fields without cooling. Two differ- ent diamond detector types are installed at LHC and CMS. One is based on pcCVD (polycrystalline chemical vapor deposition) diamonds and installed at different locations in the LHC tunnel for beam loss monitoring. Measurements of these detectors are used to perform a bunch-by-bunch beam loss analysis. They allow to disentangle the origin of beam losses. The second type uses scCVD (single crystal chemical vapor deposition) diamonds and is located inside CMS for van-der-Meer scan, beam halo and online lumi- nosity monitoring and around the LHC tunnel for beam loss observation. Results on the performance of these detectors will be presented and examples of the use for analyzing the beam conditions will be given. In order to persist the en- hanced requirements of the LHC after the long shutdown, e.g. higher luminosity, an upgrade of the detectors is re- quired. The concept of the new detectors will be presented and first results will be shown.

Physics::Instrumentation and Detectors ,Accelerators and Storage Rings - Abstract
A novel detector system has been designed for an efficient online measurement of the machineinduced background in the CMS experimental cavern. The suppression of the CMS cavern background originating from pp collision products and the 25 ns bunch spacing have set the requirements for the detector design. Each detector unit will be a radiation hard, cylindrical Cherenkov radiator optically coupled to an ultra-fast UV-sensitive photomultiplier tube, providing a prompt, directionally sensitive measurement. Simulation and test beam measurements have shown the achievability of the goals that have driven the baseline design. The system will consist of 20 azimuthally distributed detectors per end, installed at a radius of r ~ 180 cm and a distance 20.6 m away from the CMS interaction region. The detector units will enable a measurement of the transverse distribution of the bunchby- bunch machine induced background flux. This will provide important feedback from the CMS on the beam conditions during the LHC machine setup and comparisons to expectations based on FLUKA simulations.

Physics::Accelerator Physics ,Accelerators and Storage Rings - Abstract
The objective of the CLIC Test Facility CTF3 is to demonstrate the feasibility issues of the CLIC two-beam technology: the efficient generation of a very high current drive beam, used as the power source to accelerate the main beam to multi-TeV energies with gradients of over 100 MeV/m, and stable drive beam deceleration. Results of successful beam acceleration with over 100 MeV/m energy gain are shown. Measurements of drive beam deceleration over a chain of Power Extraction Structures (PETS) are presented. The achieved RF power levels, the stability of the power production and of the deceleration are discussed. Finally, we give an overview of the remaining issues to be addressed by the end of 2011.

The CLIC Test Facility 3 (CTF3) is being built and commissioned by an international collaboration in order to test the feasibility of the proposed Compact Linear Collider (CLIC) two-beam acceleration scheme. The monitoring and control of the bunch length throughout the CTF3 complex is important since this affects the efficiency and the stability of the final RF power production process. Bunch length diagnostics therefore form an essential component of the beam instrumentation at CTF3. This paper presents longitudinal profile measurements based on Streak camera and non-destructive RF power and microwave spectrometry techniques.

- Abstract
The Compact Linear Collider, CLIC is a study for a future linear electron-positron collider based on a two-beam acceleration scheme in which a high intensity drive beam is decelerated in order to provide the power to accelerate the main beam for collision in the TeV range. The power extracted from the drive beam deteriorates the beam quality and increases the energy spread significantly. Monitoring of the beam properties is therefore challenging but essential. These challenges are being addressed experimentally at the CLIC Test Facility where up to 55% of the power is extracted from the beam in the test beam line, TBL, a small-scale version of the CLIC drive beam decelerator, leaving the beam with a very wide energy profile. For monitoring of the transverse beam profile and Twiss parameters we use Optical Transition Radiation screens and quadrupole scans. The intra-pulse train energy spectrum before and after deceleration is measured with segmented beam dumps. In this report we discuss the performance of these diagnostic devices with a particular emphasis on the large energy spread and its effect on the beam imaging techniques, and with a final outlook to the CLIC drive beam diagnostics., CLIC

High Energy Physics::Experiment - Abstract
%NA48/1 The experiment performs a search for rare $K_{\rm S}$ and neutral hyperon decays. A neutral beam is produced by 400 GeV protons striking a beryllium target. About 1/3 of the produced $K_{\rm S}$ particles live long enough to enter the decay region 6m downstream of the target. The experiment aims to an exposure of about $3 \times 10^{10}$ neutral kaon decays. The experimental apparatus is based on the existing NA48 detector, with upgraded read-out systems. Charged particles are reconstructed by a magnetic spectrometer; photons are measured by a liquid krypton calorimeter (LKr). Among the most interesting decay decay modes there are the $\pi^0 e^+ e^-$, $ 3 \pi^0$, and $\gamma \gamma$. A measurement of the $ K_{\rm S} \rightarrow \pi^0 e^+ e^-$channel, or at least a precise upper limit, will bound the indirect CP violating term in the decay $ K_{\rm L} \rightarrow \pi^0 e^+ e^-$. The branching ratio for the $K_{\rm S}$ mode the cannot be accurately predicted and therefore a measurement for this decay is necessary. The NA48/1 Single Event Sensitivity (SES) is $\sim 3 \times 10^{-10}$. Since $K^0$ and $\overline{K^0}$ are not produced in the same amount in the target, one can search for CP violation via the $K_{\rm S,L}$ interference. NA48/1 searches for $K_{\rm S,L} \rightarrow 3 \pi$ interference at small proper time. Owing to the good energy resolution provided by the LKr calorimeter, the experiment can study rare kaon decays with photons only in the final state. These decays, as for example $K_{\rm S} \rightarrow \gamma \gamma$, provide important tests of Chiral Perturbation Theory. The neutral beam is also rich in neutral hyperons. In a year of data taking (120 days of 400 GeV protons with 50\% efficiency) the experiment can collect 25000 beta decays of the neutral cascade particle ($\Xi^0$). The data should allow a definitive measurement of the {\it g1/f1} form factor and a precise measurement of the Cabibbo angle.

- Abstract
The CLIC Test Facility 3 (CTF3) is being built and commissioned by an international collaboration to test the feasibility of the proposed Compact Linear Collider (CLIC) drive beam generation scheme. Central to this scheme is the use of RF deflectors to inject bunches into a delay loop and a combiner ring, in order to transform the initial bunch frequency of 1.5 GHz from the linac to a final bunch frequency of 12 GHz. To do so, the machine's transverse optics must be tuned to ensure beam isochronicity and each ring's length can finally be adjusted with wiggler magnets to a sub millimeter path length accuracy. Diagnostics based on optical streak camera and RF power measurements, in particular frequency bands, have been designed to measure the longitudinal behaviour of the beam during the combination. This paper presents the diagnostics and recent commissioning measurements.

- Abstract
The power source of the Compact Linear Collider (CLIC) relies on the generation and deceleration of a high-intensity electron drive beam. In order to provide the best radio-frequency (RF) to beam-energy transfer efficiency, the electron beam is accelerated using fully loaded RF cavities, which leads to strong beam loading effects resulting in a high-energy transient. The stability of the RF power produced by the drive beam depends on the stability of the drive beam energy and energy spread along the pulse. The control and the monitoring of the time evolution of the beam energy distribution are therefore crucial for the accelerator performance. For this purpose segmented beam dumps, which are simple and robust devices, have been designed and installed at the CLIC Test Facility 3 (CTF3). These devices are located at the end of spectrometer lines and provide horizontal beam profiles with a time resolution better than 10 ns. The segmented dumps are composed of parallel, vertical, metallic plates, and are based on the same principle as a Faraday cup: the impinging beam current is read by a fast acquisition channel. Both FLUKA and Geant4 simulations were performed to define the optimum detector geometry for beam energies ranging from 5 MeV to 150 MeV. This paper presents a detailed description of the different steps of the design: the optimization of the detector spatial resolution, the minimization of the thermal load and the long-term damage resulting from high radiation doses. Four segmented dumps are currently used in the CTF3 complex. Their measured performance and limitations are presented in this paper. Typical beam spectra as measured in the CTF3 linac are also presented along with a description of the RF manipulations needed for tuning the beam energy spectrum., Correction in: Nuclear Instruments and Methods in Physics Research Section A: Accelerators, Spectrometers, Detectors and Associated Equipment, vol. 729, p. 963, doi: 10.1016/j.nima.2013.09.005

- Abstract
At the CLIC Test Facility 3, OTR screens are commonly used in beam imaging systems for energy and energy spread characterization in dedicated spectrometer lines. In these lines the horizontal beam size is typically of the order of one centimeter. Already in 2005 a limitation was observed resulting from a strong dependence of the intensity of the light captured by the camera, on the positionon the screen (vignetting). The severity of this effect increases with the electron energy, as the aperture of the optical system is finite and the OTR photons are emitted in asmall cone of 1/γ angle. To mitigate this effect, different shapes and surface polishing of the screens were investigated. Parabolic and diffusive OTR radiators were tested in several spectrometer lines all along the CTF3 complex.The results are presented in this paper.

The CTF3 facility is being built and commissioned by an international collaboration in order to test the feasibility of the proposed CLIC drive beam generation scheme. Central to this scheme is the use of RF deflectors to inject bunches into a Delay Loop and a Combiner Ring, in order to transform the initial bunch spacing of 1.5 GHz from the linac to a final bunch spacing of 12 GHz. The optimization procedure relies on several steps. The active length of each ring is carefully adjusted to within a few millimeters accuracy using a two‐period undulator. The transverse optics of the machine must be set-up in a way so as to ensure the beam isochronicity. Diagnostics based on optical streak cameras and RF power measurements have been designed to measure the longitudinal behaviour of the beam during the combination. This paper presents their performance and highlights recent measurements.

Physics::Instrumentation and Detectors ,High Energy Physics::Experiment - Abstract
CMS is a general purpose proton-proton detector designed to run at the highest luminosity at the LHC. It is also well adapted for studies at the initially lower luminosities. The CMS Collaboration consists of over 1800 scientists and engineers from 151 institutes in 31 countries. The main design goals of CMS are: \begin{enumerate} \item a highly performant muon system, \item the best possible electromagnetic calorimeter \item high quality central tracking \item hermetic calorimetry \item a detector costing less than 475 MCHF. \end{enumerate} All detector sub-systems have started construction. Engineering Design Reviews of parts of these sub-systems have been successfully carried-out. These are held prior to granting authorization for purchase. The schedule for the LHC machine and the experiments has been revised and CMS will be ready for first collisions now expected in April 2006. \\\\ ~~~~$\bullet$ Magnet \\ The detector (see Figure) will be built around a long (13~m) and large bore ($\phi$=5.9~m) high-field (4T) superconducting solenoid leading to a compact design for the muon spectrometer. The magnetic flux is returned through $\approx$1.5~m of saturated iron yoke (1.8~T) instrumented with muon chambers. The construction of the magnet is well advanced. It will be tested on the surface in July 2004. Three of the five barrel yokes (YB) have been assembled in the surface building at Point 5. The assembly of the endcap yokes (YB) will start in April 2001. Four good lengths of Rutherford cable and three lengths of the insert (Rutherford cable co-extruded with pure aluminium), out of 21, have been produced. Each one has a length of 2.65km. The contracts for the winding machine have been placed. \\\\ ~~~~$\bullet$ Inner Tracking \\ All high $p_t$ muons, isolated electrons and charged hadrons, produced in the central rapidity region, are reconstructed with a momentum precision of $\Delta p_t / p_t \approx$~0.005~+~0.15$p_t$ ($p_t$ in TeV). The high momentum precision is a direct consequence of the high magnetic field. The tracking volume is given by a cylinder of length 6~m and a diameter of 2.6~m. In order to deal with high track multiplicities tracking detectors with small cell sizes are used. Silicon microstrip detectors provide the required granularity and precision in the bulk of the tracking volume. Stereo information is provided by back-to-back microstrip detectors with strips at a small angle. Pixel detectors placed close to the interaction region improve the measurement of the track impact parameter and secondary vertices. High track finding efficiencies are achieved for isolated high $p_t$ tracks. It is also fairly high for tracks in jets. \\ In June 2000 the LHCC approved the `All-Silicon Tracker' to be built in a single stage. The layout has been optimized with the removal of the central support tube. A pre-production comprising 200 detectors has been launched to exercise the automated production procedure. \\ The short bunch crossing time at the LHC (25ns) places challenging requirements on the readout electronics. Furthermore, the detectors and the read-out electronics have to withstand high levels of irradiation. A test in an LHC-like bunched beam was successfully carried out to test the functionality of the full electronics chain. Beam tests using electronics designed in the 0.25$\mu$m technology have confirmed the expected performance. \\ Good progress is also being made on the electronics and mechanics of the pixel detectors. \\\\ ~~~~$\bullet$ Muon System \\ Centrally produced muons are measured three times, in the inner tracker, after the coil and in the return flux. They are then identified and measured in four identical muon stations (MB) inserted in the return yoke. Special care has been taken to avoid pointing cracks and to maximize the geometric acceptance. Each muon station consists of twelve planes of aluminium drift tubes designed to give a muon vector in space, with 100~$\mu$m precision in position and better than 1~mrad in direction. The four muon stations include RPC triggering planes that also identify the bunch crossing and enable a cut on the muon transverse momentum at the first trigger level. The endcap muon system also consists of four muon stations (ME). Each station consists of six planes of Cathode Strip Chambers. The chambers are arranged such that all muon tracks traverse four stations at all rapidities, including the transition region between the barrel and the endcaps. The last muon stations are after a total of $\geq$~20$\lambda$ of absorber so that only muons can reach them. The four muon stations lead to a redundant and robust muon system. \\ Facilities for mass production have been set up in the institutes participating in the construction of the muon chambers. One site, CIEMAT (Madrid), has built two pre-production drift tube prototype chambers using the final assembly tools and procedures. The commissioning of two more sites (Aachen and Legnaro, Padova) is nearly complete. Around thirty CSC chambers have been manufactured at Fermilab. Parts and tooling have been procured for the sites at PNPI, St. Petersburg and IHEP, Beijing. The procurement of parts for the barrel RPCs also commenced in 2000. Mass production of DTs and CSCs at various sites is expected to reach the final rates in 2001. \\ The combined (using the inner tracker as well as the muon chambers) muon momentum resolution is better than 5\% at 0.3 TeV in the central rapidity region $|\eta

Segmented beam dump ,Induced Cascade Showers ,Lead ,Physics::Accelerator Physics ,Electron linac ,Spectrometer ,CLIC Test Facility ,Copper ,Beam instrumentation - Abstract
The power source of the Compact Linear Collider (CLIC) relies on the generation and deceleration of a high-intensity electron drive beam. In order to provide the best radio-frequency (RF) to beam-energy transfer efficiency, the electron beam is accelerated using fully loaded RF cavities, which leads to strong beam loading effects resulting in a high-energy transient. The stability of the RF power produced by the drive beam depends on the stability of the drive beam energy and energy spread along the pulse. The control and the monitoring of the time evolution of the beam energy distribution are therefore crucial for the accelerator performance. For this purpose segmented beam dumps, which are simple and robust devices, have been designed and installed at the CLIC Test Facility 3 (CTF3). These devices are located at the end of spectrometer lines and provide horizontal beam profiles with a time resolution better than 10 ns. The segmented dumps are composed of parallel, vertical, metallic plates, and are based on the same principle as a Faraday cup: the impinging beam current is read by a fast acquisition channel. Both FLUKA and Geant4 simulations were performed to define the optimum detector geometry for beam energies ranging from 5 MeV to 150 MeV. This paper presents a detailed description of the different steps of the design: the optimization of the detector spatial resolution, the minimization of the thermal load and the long-term damage resulting from high radiation doses. Four segmented dumps are currently used in the CTF3 complex. Their measured performance and limitations are presented in this paper. Typical beam spectra as measured in the CTF3 linac are also presented along with a description of the RF manipulations needed for tuning the beam energy spectrum. (C) 2012 Elsevier B.V.
