Operation and performance of the CBM Silicon Tracking reference telescope

A reference tracking telescope consisting of three sta- tions based on double-sided silicon microstrip detectors h as been constructed and tested in a 2 GeV proton beam exper- iment at GSI. This proof-of-principle device designed for charged particle track measurement with high spatial reso- lution closely integrates silicon sensors with self-trigg ering front-end electronics. Each station features the full read - out of a CBM02B2 prototype detector with 2◊256 strips of orthogonal orientation and 50 µm strip pitch. Four self- triggering n-XYTER readout chips have been directly wire- bonded to the detector.
