The European Spallation Source (ESS) in Lund, Sweden will become the world's most powerful thermal neutron source. The Macromolecular Diffractometer (NMX) at the ESS requires three 51.2 x 51.2~cm$^{2}$ detectors with reasonable detection efficiency, sub-mm spatial resolution, a narrow point spread function (PSF) and good time resolution.

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. [...]

Ctr.) ; Franchi, J (CERN) ; Gallinaro, M (LIP, Lisbon) ; García, F (Helsinki Inst. of Phys.) ; Giomataris, I (IRFU, Saclay) et al.
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.

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.

The spatial dependence of the timing performance of the R3809U-50 Micro-Channel-Plate PMT (MCP-PMT) by Hamamatsu was studied in high energy muon beams. Particle position information is provided by a GEM tracker telescope, while timing is measured relative to a second MCP-PMT, identical in construction. [...]
