Abstract :
The detector for the MiniBooNE [Proposal for the MiniBooNE experiment: 〈 http://www-boone.fnal.gov/publicpages/proposal.ps 〉 ] experiment at the Fermi National Accelerator Laboratory employs 1520 8 in. Hamamatsu models R1408 and R5912 photomultiplier tubes with custom-designed bases. Tests were performed to determine the dark rate, charge and timing resolutions, double-pulsing rate, and desired operating voltage for each tube, so that the tubes could be sorted for optimal placement in the detector. Seven phototubes were tested to find the angular dependence of their response. After the Super-K phototube implosion accident, an analysis was performed to determine the risk of a similar accident with MiniBooNE.
