7. R&D toward the future : MPGD and time resolution
PICOSEC Project (AUTH/CERN/SACLAY/NCSR/USTC/..)
30ps
CsI from EP-DT-EF Thin Film and Glass Lab ( see to T. Schneider Talk)
2016 RD51/H4 SPS test beam
PICOSEC detector Concept.
Cherenkov radiator: prompt photons – well defined in time
Photocathode: photoelectrons – well defined in time/space
Thin Drift : pre-amplification, minimized effects of diffusion and of primary ionization in gas
Micromegas: signal amplification
Present/Future R&D:
Photocathode (stability)
Spark Protection
Large area and multichannel readout
In HEP… HL-LHC and experiments where timing is crucial
Outside HEP… Time Of Flight PET

8. R&D toward the future : MPGD and optical readout
Optical TPC
TPC Drift & Triple GEM
PMT (Timing)
CCD (2D readout)
Planispherical GEM
Proton Beam Monitoring
Parallax-free detection in thick drift volume (Diffractometry, pinhole Imaging)
High Space Resolution, Vey Low Material Budget (towards on-line monitoring)
TPC readout for Nuclear, Neutrino Physics
imaging (beam line monitoring, medical,…)

17. GDD group and R&D on gaseous detectors active @ CERN since late sixties.
Even if it is not the only support we are giving to current and future experiments, the R&D is the most important.
(ref in a long-time-view to the LHC upgrades for LS2 based on MPGDs)
Strong International Collaboration focused on MPGD (RD51) with strong involvement of EP-DT-DD/GDD group.
CERN (specifically EP-DT): UNIQUE environment and center of expertise for MPGD technologies. We should keep it UPDATED.. Looking for new technologies, materials, techniques..
