Quality assurance of the silicon microstrip sensors for the CBM experiment — •Iaroslav Panasenko^1,2 and Pavel Larionov³ for the CBM collaboration — ¹Physikalisches Institut, Universität Tübingen, Germany — ²Institute for Nuclear Research, Kiev, Ukraine — ³University of Frankfurt, Germany

The CBM experiment at FAIR will investigate the properties of nucler matter at extreme conditions created in ultrarelativistic heavy-ion collisions. Its core detector — the Silicon Tracking System (STS) — will determine the momentum of charged particles from beam-target interactions. The track multiplicity will reach up to 700 within the detector aperture covering the polar angle 2.5^∘ and 25^∘. High track density as well as stringent requirements to the momentum resolution (∼1%) require a system with high channel granularity and low material budget.

The STS will be constructed of about 1200 double-sided silicon microstrip sensors with 58 µm pitch and a total area of ∼4 m² with all together 2.1 million channels will be read out.

In this talk the quality assurance of double-sided silicon microstrip sensors will be discussed. This includes both visual and electrical characterization. For this purpose dedicated equipment has been set up in the clean rooms of the GSI Detector Laboratory and at Tübingen University. Results of the electrical characterization of prototype microstrip sensors CBM06 will be presented.
