Detectors with a time resolution of 20-30 ps and a reliable performance in high particles flux environments are necessary for an accurate vertex separation in future HEP experiments. The PICOSEC-Micromegas detector concept is a Micro-Pattern Gaseous Detector (MPGD) based solution addressing this particular challenge. [...]

The PICOSEC-Micromegas detector was developed for precise timing of the arrival of charged particles with a resolution bellow 30 ps. This contribution, after a brief introduction presents results concerning the PICOSEC-Micromegas response to single photoelectrons, estimation of the photoelectron yield of various photocathode types, as well as its performance to time the arrival of test beam muons.

A Multipurpose Scintillating Fibre Beam Monitor for the Measurement of Secondary Beams at CERN
/ Ortega Ruiz, Inaki (CERN) ; Fosse, Loic (CERN) ; Franchi, Jonathan (CERN) ; Frassier, Alexandre (CERN) ; Fullerton, John (CERN) ; Kral, Jiri (CERN) ; Lauener, Joel (CERN) ; Schneider, Thomas (CERN) ; Spanggaard, Jens (CERN) ; Tranquille, Gerard (CERN)
A scintillating fibre beam monitor has been developed at CERN for the measurement of low energy and low intensity secondary beams. This monitor can track the passage of individual particles up to intensities of 10⁷ particles per second per mm², over an active area of 20 cm x 20 cm, and with a spatial resolution of 1 mm. [...]

Progress on the PICOSEC-Micromegas Detector Development: Towards a precise timing, radiation hard, large-scale particle detector with segmented readout
/ Kordas, K (Aristotle U., Thessaloniki) ; Bortfeldt, J (CERN) ; Brunbauer, F (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.
This contribution describes the PICOSEC-Micromegas detector which achieves a time resolution below 25 ps. In this device the passage of a charged particle produces Cherenkov photons in a radiator, which then generate electrons in a photocathode and these photoelectrons enter a two-stage Micromegas with a reduced drift region and a typical anode region.

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
/ Bortfeldt, J. (CERN) ; Brunbauer, F. (CERN) ; David, C. (CERN) ; Desforge, D. (IRFU, Saclay) ; Fanourakis, G. (Democritos Nucl. Res. Ctr.) ; Franchi, J. (CERN) ; Gallinaro, M. (LIP, Lisbon) ; Giomataris, I. (IRFU, Saclay) ; González-Díaz, D. (Santiago de Compostela U., IGFAE) ; Gustavsson, T. (IRFU, Saclay) et al.
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). [...]
