Abstract :
A silicon microstrip detector (SSD) system for use in very-high-rate experiments was designed for experiment E77 at Fermi National Accelerator Laboratory. The detector electronics were designed using application-specific IC (ASIC) chip sets where commercial circuits where not suitable. The electronics for the SSD were designed to operate with interaction rates up to 107 interactions/sec. In addition to speed, the detector for the current run is very compact with 10000 channels of active detector in a volume of 5 cm×5 cm×10 cm. The strip pitch ranges from 25 μm in the center of the detector near the target to 100 μm pitch at the most downstream, outer edge of the detector. The readout is a latch design with efficiencies of ~95% even in the presence of radiation damage and high leakage currents. The detector and associated amplifier electronics have been operated at 20°C and were designed to operate at 8°C
