Phototube tests in the MiniBooNE experiment

The MiniBooNE neutrino oscillation experiment at Fermilab uses 1520 8-in. PMTs: 1197 PMTs are Hamamatsu model R1408 and the rest are model R5912. All of the PMTs were tested to qualify for inclusion in the detector, sorted according to their charge and time resolutions and dark rates. Seven PMTs underwent additional low light level tests. The relative detection efficiency as a function of incident angle for seven additional PMTs was measured. Procedures and results are presented.
