Abstract
We have designed the backward wave oscillator. A power-pulsed generator oscillated at 24 GHz has higher frequency than current one. It is very inportant to prevent microwave from going into the beam diode, since intence microwave will harmfully affect beam generation. Due to the axial mode operation, there exist a critial value of beam energy for the oscillation. By changing the condition at the SWS end, an enhanced performance of the K-band oversized BWO is observed in a low magnetic field region about 0.8T.
