摘要：

The quality of the 20 in. photomultiplier tubes (Hamamatsu R1449) has been greatly improved over the required specifications for using them in the 50000 ton imaging water Cherenkov detector, Super-Kamiokande. In particular, the resolution of the timing response for single-photoelectron light has been reduced to approximately 3 ns (1sigma 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.
