Progress with System Integration of the CBM Silicon Tracking Detector — •Johann M. Heuser for the CBM collaboration — GSI Helmholtzzentrum für Schwerionenforschung GmbH, Darmstadt

The Silicon Tracking System (STS) is the central detector for charged-particle track measurement and momentum determination in the CBM experiment. It comprises about 900 low-mass detector modules, based on double-sided silicon micro-strip sensors. The read-out electronics is self-triggering and capable of acquiring data without event pile-up at beam-target collision rates up to 10 MHz. The STS modules are arranged on 106 carbon-fiber support ladders, which in turn are mounted onto 18 mechanical half-units to form 8 low-mass tracking stations. Cooling of the electronics is provided at the top and bottom periphery of the units to remove about 40 kW dissipated power total. The sensors will be operated at below -5 C to limit leakage currents and radiation damage effects. The STS will be enclosed by thermally insulating walls and installed in the gap of a superconducting dipole magnet.
In the presentation, progress with the system integration of the STS detector will be discussed to meet the performance goals with respect to mechanical and operational precision as well as maintenance. The overview will include module and ladder assembly, cooling, mechanical prototyping of a unit, the powering concept, cabling within the STS box and connectivity towards the supply, control and acquisition systems.
