“…In the context of a project to upgrade the gas photon detectors of COMPASS [14] RICH-1 [5,15], we are performing an R&D programme dedicated both to establish the principles and to develop the engineering aspects of detectors of single photons based on multi-layer arrangements of THick GEMs (THGEM) electron multipliers coupled to a CsI photoconverting coating. In section 2 the THGEM-based detectors of single photons are introduced and the results obtained by our R&D studies are summarised.…”

Photon detectors based on micropattern gas detectors represent a new generation of gaseous photon detectors. In the context of a project to upgrade the gas photon detectors of COM-PASS RICH-1, we are performing an R&D programme aimed both to establish the principles and to develop the engineering aspects of photon detectors based on multi-layer arrangements of thick GEMs electron multipliers coupled to a CsI photoconverter.

The trigger system consists of scintillator signal coincidences ensuring that a beam particle has crossed the radiator and the read out electronic is based on the CMAD front end chip and the F1 TDC chip used for the COMPASS experiment [10,11].

a b s t r a c tCherenkov imaging counters requiring large photosensitive areas, the capability to stand high rates and to operate in magnetic field environments could benefit from the use of photon detectors based on THick Gaseous Electron Multiplier (THGEM) coupled to a solid state CsI photo-cathode.A systematic study of the THGEM detector response as a function of its geometrical parameters and electrodes' applied voltage has been performed. Dedicated electrostatic calculations to optimize the detector design have been accomplished. Data obtained from small photon detector prototypes operating in single photon detection mode are presented and discussed. In particular the key aspect of photo-electron extraction from the photo-cathode surface is investigated via the timing spectrum response of the detector for different electric field conditions at the photo-cathode: a comparison of the measured time distributions and the simulation results is illustrated.

“…A typical single photoelectron spectrum obtained with this prototype detector and a gas mixture of Ar:CH 4 =50:50 is shown in figure 7: effective gains around 10 6 are recently being routinely obtained in laboratory tests. A typical time spectrum for single photon signals, obtained using the electronic chain described in [16] and, in particular, the F1 TDC [17] with 108 ps bin size, is shown in figure 8: a time resolution close to 7 ns is obtained from the fit of the main component of the time spectrum. Further studies to investigate the characteristics of the time response in different conditions are foreseen.…”

The development of a large size gaseous detector of single photons, able to stably operate at high gain and high rate, and to provide good time resolution and insensitivity to magnetic field would be beneficial to future Cherenkov Imaging Counters. The detector could be based on the use of a multilayer architecture of THGEM electron multipliers coupled to a solid state CsI photocathode. A systematic study of the response of THGEM-based counters versus the geometrical
