RICH (Ring Imaging CHerenkov) counters for PID in the high momentum domain and in large acceptance experiments require photon detectors covering extended surface (several square meters) and able to accept Cherenkov photons in a wide angular range. An ideal approach is represented by gaseous photon detectors, which allow covering wide surfaces at affordable costs. The first generation of these detectors was based on the use of organic vapors. The second generation consists of CsI photocathodes and open geometry gaseous detectors (MWPC). In spite of the success of this approach, some limits of the technique arise from the bombardment of the photocathodes by the ions generated in the amplification process and by the photon feedback. A third generation of gaseous photon detectors using closed geometry, as those possible with multistage arrangements of micropattern gaseous detectors, can overcome the observed limitations. We have started an R&D programme to develop a Thick-GEM-based photon detector and we report about our initial studies. © 2009 Elsevier B.V. All rights reserved
