Abstract :
The front-end electronics and data acquisition system for the SLD barrel Cherenkov ring imaging detector (CRID) are described. The specifications for this system require a 1% charge division measurement on single e/sup -/ pulses from a wire chamber in the presence of much larger signals. Fast recovery from saturating pulses and noise levels below 2000 electrons root-mean-square for single electron pulses are required. Noise and system performance results are presented for the initial SLD engineering run data.<>
