Abstract :
The change of gain with time of two types of dynodes used in photomultipliers has been studied at several current levels and under repeated fatigue cycles. The fatigue of the photomultiplier takes place predominantly in the last few dynodes; The magnitudes and time dependence of the fatigue vary with dynode current, temperature, construction, and past history.
