Hamamatsu R1584 PMT Modifications

Abstract

Four Hamamatsu H6528 Photomultiplier Tube (PMT) assemblies were purchased by the University of Regina, to be used on the SHMS Heavy Gas Cherenkov detector. Despite the excellent gain, the H6528 signal output has two disturbing characteristics: discharges and ringing tails. In this report, we offer solutions to overcome these issues.
