Abstract :
Effective generation of high microwave pulsed power has been experimentally realized in an X-band oversized backward-wave oscillator. Special methods are taken for the mode control in the structure, whose minimum radius is significantly more than the cutoff radius. At last, a 5.4-GW output power is obtained in repetitively pulsed condition, while a 6.0-GW output power is obtained in singly pulsed condition.
