Progress report on Cerenkov ring imaging detector development

The authors present recent progress on the construction and testing of the first drift boxes and single-electron detectors as they come from the production line. These detectors will be used for particle identification using the ring imaging technique in the SLD (Standard Linear Collider Large Detector) experiment. Various experimental results are presented, including single-electron pulse height measurements as a function of gas gain, detector gating capability, uniformity of response across the wire plane, charge division performance of a single-electron signal, average pulse shape and its comparison with predicted shape, and crosstalk.<
