dynode

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

加到每光电管电极上电压决PMT设计，并由每管子型来确。

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

皮安计在最后一管电极处读取电流，此电流等阳极电流减去流过前一管电极电流。
