Abstract
Hyper-Kamiokande is a next generation large water Cherenkov detector proposed for search for proton decay and neutrino observations. A 50cm Box-and-Line dynode photomultiplier tube (B&L PMT), which exhibits excellent time and energy resolution, was newly developed for Hyper-Kamiokande. The performance of the B&L PMT was confirmed under anticipated conditions in Hyper-Kamiokande such as expected magnetic field levels, high voltages and temperature ranges. Furthermore, the uniformity of timing and collection efficiency was measured for consistency with design. Characteristics of dark rate and afterpulse were also evaluated in detail.
