dynode

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

加到每个光倍增管上的压决定于PMT的设计，并由每个管子的型来确定。

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

皮安计在最后一个倍增管处读取，此等于阳减去过前一个倍增管的。
