“New” and “Old” ideas in photon detection.
We review some aspects of new and old developments in photon detection techniques. Particular emphasize is made on connections of “new” and “old” ideas in photon detection: quite often “new” ideas are well forgotten “old” ones. Comparisons are made for some “new” ideas claimed recently with “old” ideas discussed earlier, for some ideas – more than 40 years ago. Lessons learnt in studies of old developments will help to avoid not only “bicycle invention” but also give seeds for new genuine ideas as well.
The review covers different approaches in vacuum photodetectors developments including classical photomultipliers and hybrid phototubes pushed forward for the last 50 years. Some other issues concerning WLS and light guide techniques for increasing photodetectors sensitivity are discussed too. Rather detailed discussion of large area vacuum photodetectors (classical PMTs and Hybrid Phototubes) developments are presented.
Particular attention is paid to various applications by which photodetector developments have been driven by.
