文摘

The design, construction, and performance of the CLAS Cherenkov threshold gas detector at Jefferson Lab is described. The detector consists of 216 optical modules. Each module consists of three adjustable mirrors of lightweight composite construction, a Winston light collecting cone, a 5-in. photomultiplier tube, and specially designed magnetic shielding. Efficiencies and response functions have been measured.
