R\&D results on a CsI-coated triple thick GEM-based photodetector

The very high momentum particle identification detector proposed for the ALICE upgrade is a focusing RICH using a C(4)F(10) gaseous radiator. For the detection of Cherenkov photons, one of the options currently under investigation is to use a CsI-coated triple thick GEM with metallic or resistive el...

description The very high momentum particle identification detector proposed for the ALICE upgrade is a focusing RICH using a C(4)F(10) gaseous radiator. For the detection of Cherenkov photons, one of the options currently under investigation is to use a CsI-coated triple thick GEM with metallic or resistive electrodes. We will present results from the laboratory studies as well as preliminary results of beam tests of a RICH detector prototype consisting of a CaF(2) radiator coupled to a 10 x 10 cm(2) CsI-coated triple thick GEM equipped with a pad readout and GASSIPLEX-based front-end electronics. With such a prototype the detection of Cherenkov photons simultaneously with minimum ionizing particles has been achieved for the first time in a stable operation mode. (C) 2010 Elsevier B.V.
