Origin and simulation of sparks in MPGD
/ Procureur, S (IRFU, SPhN, Saclay) ; Aune, S (IRFU, Saclay) ; Ball, J (IRFU, SPhN, Saclay) ; Charles, G (IRFU, SPhN, Saclay) ; Moreno, B (IRFU, SPhN, Saclay) ; Moutarde, H (IRFU, SPhN, Saclay) ; Sabatié, F (IRFU, SPhN, Saclay)
The development of Micro-Pattern Gaseous Detectors for high luminosity experiments requires a better understanding of the origin of the sparks in these detectors. Assuming a spark occurs whenever the electron number reaches the well known Raether limit, previous Geant4 simulations quantitatively reproduced the spark rate observed in Micromegas with high energy hadron beams.

New large-size Micromegas detectors are being developed forthe future physics program of the COMPASS experiment at CERN. Thesedetectors will have a pixelised readout in their center to detectparticles in the beam region, where the particle flux can reachseveral MHz/cm2 in nominal conditions, and will have to handlehigh intensity hadron beams (up to a few 107 hadrons/s) with adischarge rate lower than 0.01 to 0.001 discharge/s.

The ASACUSA Micromegas Tracker: A cylindrical, bulk Micromegas detector for antimatter research
/ Radics, B (RIKEN (main)) ; Nagata, Y (RIKEN (main)) ; Yamazaki, Y (RIKEN (main)) ; Ishikawa, S (Tokyo, U. Earth Sci. Astron.) ; Kuroda, N (Tokyo, U. Earth Sci. Astron.) ; Matsuda, Y (Tokyo, U. Earth Sci. Astron.) ; Anfreville, M (IRFU, Saclay) ; Aune, S (IRFU, Saclay) ; Boyer, M (IRFU, Saclay) ; Chateau, F (IRFU, Saclay) et al.
The ASACUSA Micromegas Tracker (AMT; ASACUSA: Atomic Spectroscopy and Collisions Using Slow Antiprotons) was designed to be able to reconstruct antiproton-nucleon annihilation vertices in three dimensions. The goal of this device is to study antihydrogen formation processes in the ASACUSA cusp trap, which was designed to synthesise a spin-polarised antihydrogen beam for precise tests of Charge, Parity, and Time (CPT) symmetry invariance.

Detectors with a time resolution of a few tens of picoseconds and long-term durability in high particle fluxes are necessary for an accurate vertex separation in future particle physics experiments. The PICOSEC-Micromegas detector concept is a Micro-Pattern Gaseous Detector (MPGD) based solution addressing this particular challenge. [...]

Radiation imaging with glass Micromegas

Optically recording scintillation light emitted by MicroPattern Gaseous Detectors (MPGDs) with imaging sensors is a versatile and performant readout modality taking advantage of modern high granularity imaging sensors. To allow scintillation light readout of a detector based on MicroMesh Gaseous Structure (Micromegas) technology, we have integrated a Micromegas on a glass substrate with a transparent anode. [...]

A pulsed high-voltage decelerator system to deliver low-energy antiprotons
/ Husson, A (IJCLab, Orsay) ; Kim, B H (Seoul Natl. U., Dept. Phys. Astron.) ; Welker, A (CERN) ; Charlton, M (Swansea U.) ; Choi, J J (Seoul Natl. U., Dept. Phys.

The GBAR (Gravitational Behavior of Antihydrogen at Rest) experiment at CERN requires efficient deceleration of 100 keV antiprotons provided by the new ELENA synchrotron ring to synthesize antihydrogen. This is accomplished using electrostatic deceleration optics and a drift tube that is designed to switch from -99 kV to ground when the antiproton bunch is inside – essentially a charged particle “elevator” – producing a 1 keV pulse.
