Аннотация: The quality of the 20 in. photomultiplier tubes (Hamamatsu R1449) has been greatly improved over the required specifications for using them in the 50 000 ton imaging water Cherenkov detector, Super-Kamiokande. In particular, the resolution of the timing response for single-photoelectron light has been reduced to ∼ 3 ns (1σ width), and a clear single-photoelectron peak can be seen in the pulse height distribution. The obtained characteristics of the new tubes will make it possible to upgrade the performance of the Super-Kamiokande detector. The goal of the improvement, the procedure for designing the new tubes and the measuring results concerning the characteristics are described in detail.
