摘要：

We report a detailed experimental investigation of a proximity focused HPD with 256 pads of 4 x 4 mm(2) for applications to RICH detectors. A signal to noise ratio of 16 is obtained for single photoelectrons with a low noise (ENC less than or equal to 200 e) front-end electronics and 15.7 kV acceleration voltage. A single photoelectron detection efficiency of 95% is achieved with about 1% bias from electron back scattering.
