Detector module development for the CBM Silicon Tracking System — •Anton Lymanets — Physikalisches Institut, Universität Tübingen

The central detector of the CBM experiment at FAIR, the Silicon Tracking System (STS), is being designed to reconstruct hundreds of charged particles produced at rates up to 10 MHz in interactions of ion beams of up to 45 AGeV projectile energies with nuclear targets. The building block of the tracking system is a module suitable for a low-mass detector construction. In a module, the basic functional unit of the STS, radiation tolerant microstrip sensors are read out through low-mass multi-line cables with self-triggering front-end electronics located at the periphery of the system. Light-weight carbon fibre support structures will carry 10 of such modules and build up the STS stations.

In the presentation, the concept of the detector module construction is presented. Quality assurance tests under development for the module components (double-sided silicon microstrip sensors, stacked polyimide microcables, front-end ASICs and boards) and the assembled structures are discussed.

Supported by EU-FP7 HadronPhysics3 and BMBF.
