Abstract
We report the results of a systematic study of the performance of 10 x 10 cm 2 triple-GEM detectors operated with several gas mixtures.In a previous paper, we pointed out that adding CF4 to the standard Ar/CO2 gas mixture allows to improve the time resolution of the detector from similar to10 ns down to similar to6 ns (r.m.s.). In this paper, we discuss the results obtained with CF4 and iSO-C4H10-based gas mixtures, during a beam test at the piM1 beam facility of the Paul Scherrer Institute (PSI).Preliminary results concerning the discharge probability of triple-GEM detector, when exposed to both high intensity pion/proton beam and alpha-particles from a radioactive source are presented. Gain measurements and aging tests, using a high intensity 5.9 keV X-ray tube, are eventually discussed. (C) 2002 Elsevier Science B.V. All rights reserved.
