摘要: Abstract In the field of large scale water Cherenkov experiments such as proton decay, detector is required to have a wide photosensitive area, high gain, low noise, fast timing, and good stability. The 20 inch diameter photomultiplier developed ascertained characteristics component decay experiment. this paper, various newly 20″ PMT are described.
