36. Development of DLC-RPC for Radiative Decay Counter of MEG II Experiment

Atsuhiko Ochi (Kobe University (JP))

14/12/2022, 09:00

The RPC with very thin material budget using MPGD technology has been developed for MEG- II experiment; muon to positron + gamma rare decay experiment. To improve the background rejection, low energy (< a few MeV) positrons coming from radiative decay should be detected under intense muon beam (around 4 x 106 muons per unit cm2) penetrating in the detector. Very small material budget (<0.001 x...

37. The surface Resistive Plate Counter (sRPC): an MPGD technology based RPC

Matteo Giovannetti (INFN e Laboratori Nazionali di Frascati (IT))

The Surface Resistive Plate Counter (sRPC) is a novel RPC based on surface resistivity electrodes, a completely different concept with respect to traditional RPCs that use electrodes characterized by volume resistivity. The electrodes of the sRPC exploit the well-established industrial Diamond-Like-Carbon (DLC) sputtering technology on thin (50μm) polyimide foils, already introduced in the...

38. Studying signals in particle detectors with resistive elements such as the 2D resistive-strip bulk Micromegas.

Djunes Janssens (Vrije Universiteit Brussel (BE))

The uninterrupted advancements of modelling and simulation tools, such as Garfield++, has guided the widespread development and understanding of particle detector technologies. Since novel detector structures are proposed regularly, with resistive detectors becoming an ever-increasing fraction of these, it is vital to reflect this progress in the capabilities of the modelling tools. This talk...

39. Design, production and performances of the Encapsulated Resistive Anode Micromegas detectors for the readout of the High-Angle TPCs of the upgrade of the T2K Near Detector

Alain Delbart (Université Paris-Saclay (FR))

14/12/2022, 10:00

The long baseline neutrino experiment T2K will upgrade its near detector (ND280) next year to reduce the systematic uncertainty to less than 4% by adding an active highly segmented neutrino target (Super Fine Grained Detector) surrounded by two new gaseous Time Projection Chambers (High-Angle TPCs) and a 4p TOF veto. The required performances of these TPCs for momentum measurement and particle...

40. A neutron detector with RWELL in 3He-CF4 gas mixtures

Davide Raspino (STFC)

The MSGC was the earliest MPGD and the only type found able to operate in 3He-CF4 gas mixtures with a CF4 partial pressure of several atmospheres. This was until our work on the μRWELL, the most recently developed MPGD. Our investigations were the first to test 3He as a neutron converter with the μRWELL and we found we could safely use at least six bar of CF4. Despite the 3He shortage,...

41. Cryogenic RWELL: high gain with quenched discharges

Andrea Tesi (Weizmann Institute of Science (IL))

"Large volume Liquid Argon (LAr) Time Projection Chambers (TPC) are the technology of choice to study the elusive nature of neutrinos and to search for dark matter (DM) particles. Within the volume of noble liquid, neutrino or DM interactions produce prompt scintillation light and ionization electrons. The former is readout using UV light sensors while the latter are drifted under the...
