First results of VLSI Front End Electronics for photo detectors

The upgrade of the CLEO detector has finished with the installation of the new silicon detector in February 2000. The detector is a four layer barrel-style device with double-sided silicon detectors. It spans the radial distance from 2.5 cm to 10.2 cm and cover 93% of the solid angle surrounding the interaction region. The innermost layer is 16 cm, the outermost is 55 cm long. Important features of the new design are a very small radiation length of the detector material and new front-end electronics to deal with the capacitive load of the long silicon wafer chains. First results of the detector performance will be presented.

The Belle II experiment integrates two dedicated particle identification (PID) subdetectors for pion/kaon separation. The Aerogel Ring Image Cherenkov (ARICH) detector is a forward region PID detector based on two layers of aerogel read out by hybrid avalanche photo detectors. The Time of Propagation (TOP) detector is a novel Cherenkov barrel PID system built for the Belle II detector upgrade based on quartz radiator bars read out by Micro-Channel Plate PMTs. The readout electronics of the TOP system are built around a switched capacitor array waveform sampling ASIC operating at 2.7 GSa/s. Acquired waveforms are processed in real time in the front-end electronics, extracting the individual timing of detected photons to better than 100 ps. This contribution presents the concept of the Belle II particle identification systems with a focus on the current status of commissioning, calibration and operation of the Belle II TOP detector.
