Abstract

The Silicon Tracking System, Muon Chamber, Transition Radiation Detector and Time-Of-Flight among others are the detector systems of the Compressed Baryonic Matter (CBM) experiment at the FAIR facility. These detector systems will be built with tens of thousands of front-end ASICs exposed to high radiation doses and difficult environmental and interference conditions. A CERN's GBTx-based solution was chosen for combining data from multiple front-end ASICs into an optical link before further concentration and preprocessing in the common Data Processing Board data hub. This paper presents the protocol design addressing the DAQ system requirements, simplifying the ASIC's back-end design and presents its adaptation for the STS and MUCH detector's conditions. A specific link synchronization technique, hit data bandwidth optimization and time synchronization method for the self-triggered front-end chip are presented.
