dynode

The voltages that should be applied to each dynode are a function of PMT design and are specified for each tube type.

加到每光电倍增电极上的电压决于PMT的设计，并由每的型来确。

The picoammeter reads the current at the last dynode, which is equal to the anode current minus the current flowing to the previous dynode.

计在最后一倍增电极处读取电流，此电流等于阳极电流减去流过前一倍增电极的电流。
