摘要：
A operating circuit and control method for protecting a PMT having a photocathode, a plurality of dynodes and an anode against overloading with a shorter reaction time, and to allow it to be switched on again rapidly. For this purpose, a switch is provided for electrically short circuiting the photocathode with the first dynode, or a switch is provided for reversing the polarity of the voltage between the photocathode and the first dynode.
