Popis:	The two most important parameters characteristic of multiplier phototubes are: γ, the photoanodic sensitivity factor (which is the number of amperes produced at the photoanode to the watts of radiant power reaching the photocathode) and BM, the effective gain of the multiplier phototube. M is the actual gain of the multiplier phototube (M=Gx, where G is the gain per dynode and x is the number of dynodes) and B is a statistical factor which accounts for electrons produced at the dynodes and for electrons lost in the transit from cathode to anode.
