Integration of the CBM Silicon Tracking System — •Ulrich Frankenfeld — GSI Helmholtzzentrum für Schwerionenforschung GmbH
The Silicon Tracking System of the CBM experiment will be installed into the superconducting dipole magnet, sharing the confined space of about 2 m3 with the target and the micro-vertex detector, operating in a separate vaccum vessel, and the beam pipe. The STS stations will be surrounded by a thermal enclosure to minimize radiation damage to the silicon sensors.
For the system integration task, a top-down approach has been chosen, starting from the physics requirements of the CBM experiment: interaction rates, radiation environment, tracking aperture and detector segmentation. A functional plan of the STS and its surrounding structural components is being worked out from which the STS system shape is derived and the power need, cooling, the connector and cable space requirements, live span of components, and installation/ repair aspects etc. are determined. The presentation will outline the technological options under study and progress made with the system integration of CBM’s central detector.
Supported by EU-FP7 HadronPhysics3, CRISP, BMBF, GSI, JINR and ROSATOM.
