Description

The PICOSEC Micromegas (MM) precise timing detectors offer precise timing on the order of tens of ps by coupling a Cherenkov radiator with a photocathode and a MM amplification structure. Time resolution below 25 ps for MIPs was demonstrated with single-channel prototypes. Recent developments towards instrumenting larger detection areas with precise timing PICOSEC detectors include multi-channel tileable detector modules, resistive MM, alternative photocathode materials, and custom readout electronics.
Timing performance for signals shared across multiple pads was confirmed to be comparable to single-channel results in a previous multi-pad prototype with corrections for non-uniformity of the preamplification gap. A fully tileable 100-ch, 100 cm$^2$ detector prototype based on the rigid ceramics/FR4 substrate was commissioned. Test beam campaigns showed improvement of the timing response uniformity reaching 26 ps pad level time resolution.
Different readout options including custom preamplifiers and fast charge-sensitive preamplifiers together with digitisation with SAMPIC were investigated to enable readout of 100-ch modules.
The scalability to large detection areas, excellent timing resolution, and flexibility in readout granularity which can enable spatial resolution make PICOSEC Micromegas detectors an attractive technology for precise timing detector systems as well as fast photon detectors.
