Gigawatt S-band frequency-tunable HPM sources

The paper describes S-band HPM sources developed at IHCE: the resonant BWO producing /spl sim/5 GW, 100 J pulses, based on the SINUS-7 electron accelerator, and a double-section vircator with peak power of /spl sim/1 GW and pulse width of 20-50 ns, fed from either SINUS-7 accelerator or MARINA inductive-store pulse driver with fuse opening switch.
