Quantum Efficiency
Every PMT has a so-called "quantum efficiency" associated with it. These is the efficiency of the PMT photocathode window converting photons into electrons quantum mechanically via the photoelectric effect. Typically these percentages hover around ~20%. In any case, it is an important property to know about the PMTs that will be used for the Kaon Aerogel Cherenkov Detector.
