Investigations on the Operational Behavior of the GEM MSGC Inner Tracking System and Study on the Reconstruction of chi_c Events in the HERA-B Detector
This thesis reports about the operation of the inner tracking system of HERA-B. In the year 2000 this large system of GEM MSGC detectors was commissioned. The operational behavior of the delicate chambers in the difficult environmental conditions caused by the hadronic particle beam of HERA-B was studied over a long period of time. During the operation period in 2000 stable operational conditions were established and a procedure was developed and implemented to condition the chambers to the operation in the particle beam. In the second part of this thesis, a study to reconstruct chi_c events is presented. Data taken by HERA-B in 2000 was used. The chi_c signal was established in data taken from proton-carbon and proton-titanium interactions.
