Abstract The PICOSEC Micromegas (MM) detector is a precise timing gaseous based on MM operating in two-stage amplification mode and Cherenkov radiator. Prototypes equipped with cesium iodide (CsI) photocathodes have shown promising time resolutions as 24 picoseconds (ps) for Minimum Ionizing Particles. However, due to the high hygroscopicity susceptibility ion bombardment of CsI photocathodes, alternative photocathode materials are needed improve robustness MM. Diamond-like Carbon (DLC) film...
Abstract PICOSEC Micromegas (MM) is a precise timing gaseous detector based on Cherenkov radiator coupled with semi-transparent photocathode and an MM amplifying structure. The concept was successfully demonstrated through single-channel prototype, achieving sub-25 ps time resolution Minimum Ionizing Particles (MIPs). A series of studies followed, aimed at developing robust, large-area, scalable detectors high resolution, complemented by specialized fast-response readout electronics. This...
