Support and control system for suspension electrode of double-gap series diode

The support and control system of double-gap series diodes suspension electrode was developed. It consists of support pins, driver circuit and synchronization control part. The support pins are retracted using three small solenoids, and the suspension electrode is accurately located by the three support pins. The withdrawing support pins are driven by a capacitor discharge, and with the driving, the pins can move 30 mm and the suspension electrode can move 125 m in 5 ms. The voltage signal of magnetic coil is used as the synchronization control signal. It triggers the time delay unit DG535, which may export a pulse delayed by 5 ms and trigger the forestage trigger source of Flash-Ⅱ. The Flash-Ⅱ starts at the same time when the support pins withdraw from the diode space. The experimental results indicate that the double-gap series diode is reliable with the suspension electrodes support and control system.
