Quality Assurance of double-sided silicon microstrip sensors for the Silicon Tracking System in the CBM experiment at FAIR — •Pavel Larionov for the CBM collaboration — Goethe Universität, Frankfurt

The Silicon Tracking System (STS) is the core tracking detector of the CBM experiment at FAIR. The system’s task is to reconstruct the trajectories of the charged particles produced in the beam-target interactions, provide their momentum determination, and enable the detection of decay topologies. The STS will comprise 1220 double-sided silicon microstrip sensors. After production each sensor will go through a number of Quality Assurance procedures to verify their validity for performance in the STS and also to confirm the manufacturer’s data. In this talk, results of the quality assurance procedures that are being applied to the latest STS prototype sensors, including detailed tests of the quality of each single strip, long-term stability and preparations for volume tests during series production, will be presented. Supported by HIC for FAIR, HGS-HIRe and H-QM.
