Description
The advent of the first generation of neutrino telescopes gave impetus to the development of hybrid phototubes with luminescent screens. The phototubes have been used in the two pioneering neutrino telescope projects - Deep Underwater Muon and Neutrino Detector (DUMAND) in the Pacific Ocean and the Lake Baikal neutrino experiment. In this paper we summarize a wealth of experience accumulated in a time of the development of the phototubes and operation of arrays using the phototubes as basic detecting elements. Extensive experimental data on the phototubes (sensitivity, time and amplitude resolutions, dark current, stability etc) are presented. Some technological problems encountered, solved and still existing, are discussed. It is shown that even with existing technologies the phototubes are the most adequate photodetectors for large scale deep underwater neutrino telescopes. Some issues concerned with future developments of the phototubes (technological improvements, optimization and improvement of the phototube performance etc) based on our present day knowledge are discussed too.
