Abstract :
The LHCb detector is a collider experiment at the new LHC at CERN/Switzerland. It is dedicated to measure precisely CP violation parameters in the B-system. The LHCb Silicon Tracker is covering the regions of the tracking detector with the highest particle fluences. The silicon sensors are wide pitch strip detectors connected to multi-channel analogue readout amplifiers. The analogue data is then digitized and transmitted optically to the counting room for further processing. The following paper describes R&D of the silicon sensors performed including testbeam data. We present readout chip performance followed by an overview of the used data transmission system, which has been designed for radiation tolerance and low cost.
