Abstract :
A facility to test the photomultiplier tubes (PMTs) for the Sudbury Neutrino Observatory (SNO) was constructed at Queenʹs University. The facility measured the noise rate, relative efficiency, and charge and time spectra of single photoelectron anode signals for 44 PMTs daily. The system is described, and detailed results of the testing for two particular PMTs are presented as well as statistics for 9829 Hamamatsu R1408 PMTs accepted for use in SNO.
