Abstract

Abstract

A compact repetitive PFN-Marx generator was constructed for the application of generating electron beams. The generator has twenty-two stages with inductive isolation. Each stage consists of twenty-one ceramic capacitors which may be charged the maximal voltage of 60 kV by a pulse transformer in 50 s. A compact Marx trigger with the integrated design of a pulse transformer and a magnetic switch which have a common magnetic core was also fabricated. The generator can operate at 5 Hz rep-rate with the output power of 7 GW, the impedance of 40 and the pulse width of 100 ns. Changing the capacitor units, an improved generator with the impedance of 50 and the pulse width of 70 ns generates ten pulses of one burst with the power of 8 GW at 10 Hz rep-rate. An S-band magnetron driven by the improved generator has generated microwave output with the power of 1 GW at the frequency of 2.32 GHz, which preliminarily shows the generators ability of driving high power microwave devices.
