Optical quality assurance procedures for the sensors of the CBM Silicon Tracking System — •Evgeny Lavrik for the CBM collaboration — Physikalisches Institut der Universität Tübingen, Tübingen, Deutschland

The Compressed Baryonic Matter (CBM) experiment at FAIR aims to study the properties of nuclear matter at high net-baryon densities. The Silicon Tracking System is the key detector to reconstruct charged particle tracks created in heavy-ion interactions. In order to assure the quality of more than 1000 silicon sensors including spares, highly efficient and highly automated procedures need to be developed.

In this contribution we report on the optical quality assurance setup built at the University of Tübingen and the progress in the development preparing for the mass inspection of the silicon sensors arriving from the manufacturers in 2017. We will as well as summarize the results and experience obtained from inspecting prototype sensors.
