n.倍增器電極(二次放射極；打拿極)

The voltages that should be applied to each dynode are a function of PMT design and are specified for each tube type. 加到每個光電倍增管電極上的電壓決定于PMT的設(shè)計，并由每個管子的型號來確定。

Electrons are accelerated by making the voltage of each successive dynode of the tube more positive than the previous one. 使每個連續(xù)的光電倍增管電極的電壓都比它前面一個電極的電壓更高，這樣電子就得到加速。

The picoammeter reads the current at the last dynode, which is equal to the anode current minus the current flowing to the previous dynode. 皮安計在最后一個倍增管電極處讀取電流，此電流等于陽極電流減去流過前一個倍增管電極的電流。

Our purpose is to deposit MgO films by reactive R.F. sputtering deposition, we completed the dynode devices on INVAR substrates. 濺鍍制程是現(xiàn)今許多高科技元件的關(guān)鍵技術(shù)，因此薄膜的基礎(chǔ)科學及相關(guān)制程技術(shù)的研發(fā)為現(xiàn)今學術(shù)界及產(chǎn)業(yè)界的重大課題。

The easiest way to accomplish this is to apply a potential across the entire tube and tap the dynode voltages off a voltage divider, as shown in Figure 4-13. 做到這一點最容易的方法是給整個光電倍增管的兩端加上一個電壓，然后從一個分壓器的各個抽頭取得供給各個倍增管電極的電壓，如圖4-13所示。
