Proton beam tests of silicon microstrip sensors for the CBM experiment — •Maksym Teklishyn1,2, Olga Bertini3, Johann Heuser3, Anton Lymanets3,2, Hanna Malygina3,4,2, and Ievgeniia Momot3,4,2 for the CBM collaboration — 1FAIR, Darmstadt — 2KINR, Kyiv, Ukraine — 3GSI Helmholtzzentrum für Schwerionenforschung GmbH, Darmstadt — 4Goethe Universität Frankfurt
The physics aim of the Compressed Baryonic Matter (CBM) experiment is to explore the phase diagram of strongly interacting matter at highest net baryon densities and moderate temperatures in the range reachable with heavy ions collisions between 2−45 AGeV, initially 2−14 AGeV (SIS 100).
Double-sided 300 µ m thick silicon microstrip sensors are planned to be used in the Silicon Tracking System (STS). The performance of recent sensor prototypes was studied with the beam of 1.6 GeV/c protons at COSY, Jülich. The Alibava system, based on the Beetle front-end chip, served as read-out electronics.
We performed various tests with the sensor prototypes: the charge collection efficiency was studied for the set of connection schemes for the different penetration angles of incident particles. The analysis of the data, collected with the proton beam, improves our understanding of the charge collection mechanism, relevant for the sensor production readiness.
