Control system of repetitively pulsed intense-electron-beam accelerator charged by capacitive energy storage

A remote trigger-control system based on LabVIEW and PIC microcontroller is developed to control the repetitively pulsed intense-electron-beam accelerator charged by capacitive energy storage. This system employs an ordinary data-acquisition card and a microcontroller to realize complex circuit control and sequence control, with functions of signal collecting, data sheet calling, thyristor switch triggering and so on, to achieve the main purpose of controlling the charging of primary capacitance of transformer resonantly and stably. When the intense-electron-beam accelerator works repetitively with the control system, the voltage of the primary capacitance of transformer is tested to be consistent and stable, which shows that the control system can work stably and reliably with strong anti-interference ability.
