“…-8 -Secondary emission yields of GaP(Cs) surfaces are considerably higher, typically between 30 and 50 at a primary electron energy of 600 eV, than those obtained with conventionil dynode materials, where average dynode gains of 5 to 8 can be achieved [19], [20], Due to the higher secondary emission yield, photomultiplier electron multipliers require a fewer numbers of dynode stages than conventional electron multipliers for the same gain.…”

The optimum operating conditions of the photomultipliers have been determined for minimum time spread and relative collec tion efficiency. The error of the time spread measurements, because of the finite width of the light pulse, is discussed and determined for different pulse widths.
