Two pulses generated by two FCGs driving a single modulator
The explosively-driven flux compression generators(FCGs) are always used to drive pulse modulators,and high power pulses can be generated on the diodes.In this paper,two dynamically cascaded FCGs were ignited one after another to drive a modulator made up of a pulsed transformer and a pulse forming line(PFL).The two FCGs were controlled by a selftimer with 20 ms interval and the electrical isolation between them was achieved by two fuses.Two pulses with peak power more than 20 GW and pulse interval 20 ms were generated on the diode.The experiment shows that multiple pulses could be obtained by a single modulator if more driving FCGs are used.This method could test the pulsed power apparatus' electricity recovery characteristics,which are necessary to build high power and high repetitious frequency accelerators.
