Quality assurance tests of the CBM Silicon Tracking System sensors with an infrared laser — •Maksym Teklishyn for the CBM collaboration — FAIR GmbH, Darmstadt — KINR, Kyiv, Ukraine

Double-sided 300 µm thick silicon microstrip sensors are planned to be used in the Silicon Tracking System (STS) of the future CBM experiment. Different tools, including an infrared laser, are used to induce charge in the sensor medium to study the sensor response. We use present installation to develop a procedure for the sensor quality assurance during mass production. The precise positioning of the laser spot allows to make a clear judgment about the sensor interstrip gap response which provides information about the charge distribution inside the sensor medium. Results are compared with the model estimations. Supported by EU-Horizon 2020 CREMLIN.
