Research output: Contribution to journalArticlepeer-review


An automatic system for testing up to 32 photomultiplier tubes (PMs) simultaneously under single photon counting conditions has been used to measure characteristics of more than 2500 PMs for use in the Irvine-Michigan-Brookhaven (IMB) proton decay experiment, 2048 tubes (64 EMI 9834B 8″ diameter, and 1984 EMI 9870B 5″ diameter) were selected for use in the 8000 m3 IMB water Cherenkov detector, now in operation for over a year. The PM test system is described and results of testing are presented along with PM performance in the IMB detector over the last year. In general, we find that the tube characteristics have smaller fluctuations than expected and that the tubes have proven to be reliable under rugged handling and operating conditions. On the basis of our experience, we make suggestions as to new industry standards for PMs to be used in particle counting.
