A small series production of detector modules made of MicroStrip Gas Counters (MSGC) and a Gas Electron Multiplier (GEM) foil has been exposed to a high-intensity hadron beam, We report about the reproductibility and stability of the detector responses and about the occurrence and consequences of discharges in the detector, The interdependence of the four voltage differences used in the detector has been studied by Simulation and with X-ray measurements. Rate dependence of the signal amplitude is observed. The behaviour of the MSGC + GEM is compared to that of a state-of-the-art MSGC. Influence of various parameters on the detector response is investigated. (C) 2002 Elsevier Science B.V. All rights reserved.
