Development of micro pattern gas detectors for high rate experiments

Since the introduction of Micro Strip Gaseous Chambers (MSGC) and Gas Electron Multipliers (GEM) in the early 90s, a large family of different Micro Pattern Gas Detectors (MPGD) has grown, offering high rate capability and an excellent position accuracy. A combined system of MSGC and GEM was developed for the inner tracking system of the Hera-B experiment at DESY Hamburg. In this thesis, the principles of electron transfer in the GEM and, in addition, discharging and ageing effects were studied in various conditions. Results from a final beam test in real conditions are reported, proving that this detector can survive the harsh operation conditions of the Hera-B experiment.
