/ Papaevangelou, Thomas (IRFU, Saclay) ; Desforge, Daniel (IRFU, Saclay) ; Ferrer-Ribas, Esther (IRFU, Saclay) ; Giomataris, Ioannis (IRFU, Saclay) ; Godinot, Cyprien (IRFU, Saclay) ; Gonzalez Diaz, Diego (CERN) ; Gustavsson, Thomas (LIDYL, Saclay) ; Kebbiri, Mariam (IRFU, Saclay) ; Oliveri, Eraldo (CERN) ; Resnati, Filippo (CERN) et al.
The current state of the art in fast timing resolution for existing experiments is of the order of 100 ps on the time of arrival of both charged particles and electromagnetic showers. Current R&D; on charged particle timing is approaching the level of 10 ps but is not primarily directed at sustained performance at high rates and under high radiation (as would be needed for HL-LHC pileup mitigation).

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.

PICOSEC: Charged particle timing at sub-25 picosecond precision with a Micromegas based detector

The prospect of pileup induced backgrounds at the High Luminosity LHC (HL-LHC) has stimulated intense interest in developing technologies for charged particle detection with accurate timing at high rates. The required accuracy follows directly from the nominal interaction distribution within a bunch crossing ($\sigma_z\sim5$ cm, $\sigma_t\sim170$ ps). [...]
