    • An electronic circuit for protecting a photomultiplier against overloads is provided. The photomultiplier has a cathode, an anode, a plurality of dynodes and a voltage divider. The circuit includes a high-voltage source, which applies a high voltage to the photomultiplier. A protective switch is set up for preventing a current flow through the anode. A comparison device is configured for comparing a load signal characterizing the loading of the anode with a maximum load signal and for driving the protective switch in accordance with this comparison.
    • 提供了用于保护光电倍增器免受过载的电子电路。 光电倍增管具有阴极,阳极,多个倍增电极和分压器。 该电路包括高电压源,其向光电倍增管施加高电压。 设置保护开关用于防止电流流过阳极。 比较装置被配置为将表征阳极负载的负载信号与最大负载信号进行比较,并根据该比较来驱动保护开关。
