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.

Photocathode characterisation for robust PICOSEC Micromegas precise-timing detectors
/ Lisowska, M. (CERN ; IRFU, Saclay) ; Aleksan, R. (IRFU, Saclay) ; Angelis, Y. (Aristotle U., Thessaloniki) ; Aune, S. (IRFU, Saclay) ; Bortfeldt, J. (Munich U.) ; Brunbauer, F. (CERN) ; Brunoldi, M. (Pavia U. ; INFN, Pavia) ; Chatzianagnostou, E. (Aristotle U., Thessaloniki) ; Datta, J. (SUNY, Stony Brook) ; Dehmelt, K. (Jefferson Lab) et al.
The PICOSEC Micromegas detector is a~precise-timing gaseous detector based on a~Cherenkov radiator coupled with a~semi-transparent photocathode and a~Micromegas amplifying structure, targeting a~time resolution of tens of picoseconds for minimum ionising particles. Initial single-pad prototypes have demonstrated a~time resolution below 25 ps, prompting ongoing developments to adapt the concept for High Energy Physics applications, where sub-nanosecond precision is essential for event separation, improved track reconstruction and particle identification.

/ Allard, J. (IRFU, Saclay) ; Andari, N. (IRFU, Saclay) ; Anfreville, M. (IRFU, Saclay) ; Attié, D. (IRFU, Saclay) ; Aubernon, E. (IRFU, Saclay) ; Aune, S. (IRFU, Saclay) ; Bachacou, H. (IRFU, Saclay) ; Balli, F. (IRFU, Saclay) ; Bauer, F. (IRFU, Saclay) ; Beltramelli, J. (IRFU, Saclay) et al.
The steadily increasing luminosity of the LHC requires an upgrade with high-rate and high-resolution detector technology for the inner end cap of the ATLAS muon spectrometer: the New Small Wheels (NSW). In order to achieve the goal of precision tracking at a hit rate of about 15 kHz/cm$^2$ at the inner radius of the NSW, large area Micromegas quadruplets with 100 \microns spatial resolution per plane have been produced.

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.
