Abstract：
A backward wave oscillator (BWO) is introduced in the paper. On the accelerator of Sinus-700, it is experimentally investigated. Under the condition that the electron energy is 740keV, the beam current is 7kA and the guiding magnetic field is at 0.68T, the performance of 1.15GW microwave output power at. 9.1GHz microwave frequency with 22ns pulse width and 22% conversion efficiency are reached.
