【 摘 要 】

The operation of different avalanche photodiodes (APDs) for detection of liquid xenon scintillation was investigated. Quantum efficiencies of 1.08 plus or minus 0.05 and 0.80 plus or minus 0.14 where measured for two APD's provided by Advanced Photonix Inc. (API) and Hamamatsu Photonics, respectively. Both APD types were found to reach gains above 200, although gains as low as a few tens may prove sufficient to achieve optimum performance. Compared to the API photodiodes, the Hamamatsu APDs used in these tests exhibited poor performance.
