A radiation tolerant fiber-optic readout system for the LHCb Silicon Tracker

A fiber-optic readout system has been designed for the LHCb Silicon Tracker to transmit the detector data to the counting room at a distance of 120 m from the detectors. In total, data from over 272000 detector channels have to be transmitted at an average trigger frequency of 1.1 MHz. In the design...

Sumario:A fiber-optic readout system has been designed for the LHCb Silicon Tracker to transmit the detector data to the counting room at a distance of 120 m from the detectors. In total, data from over 272000 detector channels have to be transmitted at an average trigger frequency of 1.1 MHz. In the design of the system, special attention was given to its radiation tolerance, as the transmitting section is located close to the beamline and therefore is exposed to moderate particle fluences and ionizing dose during the expected operational life of 10 years. We give a general overview of the readout link scheme and present performance data on its reliability and radiation tolerance obtained from first preseries elements of the system. Poster presented on the 10th European Symposium on Semiconductor Detectors, June 12th â€" June 16th 2005, Wildbad Kreuth, Germany.
