Abstract
Characterization of a large number of visible Light photon counters (V LPC) is an integral part of the scintillating fiber system test for th e D0 upgrade, currently underway at Fermilab. We report results from o ur investigation of 4200 channels of HISTE IV VLPC's, for use in a cos mic ray test. We have studied the dependence of critical device charac teristics Like quantum efficiency, gain, and noise as a function of op erating temperature and VLPC bias voltage, and the variation of these characteristics over the large sample. We also discuss the general ope ration of the devices and the problems encountered during the characte rization.
