An automated testing procedure for microstrip sensors for the CBM silicon tracking system

The goal of the CBM experiment at FAIR is to explore the QCD phase diagram in the region of high net-baryon densities and moderate temperatures. The Silicon Tracking System (STS), the core tracking detector of the CBM experiment, is located close to the target and is used to reconstruct charged particle trajectories and its momenta in nucleus-nucleus collisions. The tracking stations will be mounted with ∝1200 double-sided silicon microstrip sensors which have to be tested before installation. For mass testing, automated quality assurance procedures are required to save both time and manpower. The performance of the developed program and the measurement results for different prototype sensors will be presented.
