Abstract：
The BWO(Backward-Wave Oscillator) slow-wave structure was optimized by the KARAT code, and the experiment was performed at the RADAD303 accelerator flat under the condition of the electron beam with the voltage of 177kV, the current of 785A, and magnetic field of 1.7T. TE ₁₁mode millimeter wave was generated, whose peak powe is 18MW, frequency 39.8GHz and pulse duration 3ns.
