Quality assurance of the CBM Silicon Tracking System sensors — •Evgeny Lavrik for the CBM collaboration — Facility for Antiproton and Ion Research, Darmstadt, Germany
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 1100 silicon sensors including spares, highly efficient and highly automated procedures were developed.
In this contribution we report on the optical and electrical quality assurance procedures for silicon sensors. We describe dedicated hardware setups to perform basics tests and full characterization and their application for the quality assurance of the STS sensors. We present the results of ongoing QA campaign of sensors from mass production which begun in November 2019.
