Precise timing and recent advancements with segmented anode PICOSEC Micromegas prototypes
/ PICOSEC-Micromegas Collaboration
Timing information in current and future accelerator facilities is important for resolving objects (particle tracks, showers, etc.) in extreme large particles multiplicities on the detection systems. The PICOSEC Micromegas detector has demonstrated the ability to time 150 GeV muons with a sub-25 ps precision. [...]

Charged particle timing at sub-25 picosecond precision: the PICOSEC detection concept
/ Iguaz, F.J. (IRFU, Saclay) ; Bortfeldt, J. (CERN) ; Brunbauer, F.M. (CERN) ; David, C. (CERN) ; Desforge, D. (IRFU, Saclay) ; Fanourakis, G. (Democritos Nucl. Res. Ctr.) ; Franchi, J. (CERN) ; Gallinaro, M. (LIP, Lisbon) ; García, F. (Helsinki U.) ; Giomataris, I. (IRFU, Saclay) et al.
The PICOSEC detection concept consists in a "two-stage" Micromegas detector coupled to a Cherenkov radiator and equipped with a photocathode. A proof of concept has already been tested: a single-photoelectron response of 76 ps has been measured with a femtosecond UV laser at CEA/IRAMIS, while a time resolution of 24 ps with a mean yield of 10.4 photoelectrons has been measured for 150 GeV muons at the CERN SPS H4 secondary line.

The PICOSEC-Micromegas (PICOSEC-MM) detector is a novel gaseous detector designed for precise timing resolution in experimental measurements. It eliminates time jitter from charged particles in ionization gaps by using extreme UV Cherenkov light emitted in a crystal, detected by a Micromegas photodetector with an appropriate photocathode.
