This paper brings forth a new relativistic backward-wave oscillator with axial extracting. Numerical simulation is conducted using KARAT code. This simulation produces a microwave pulse power of 2.0GW at 9.28GHz for 730 kV, 6kA injecting beam. Power transform efficiency of 45% is obtained. The interaction between beam and slow wave structure is tracked and analyzed. SUPERFISH code is used to calculate axial electric field distribution, and the results shows that the relativistic backward-wave oscillator with axial extracting has the advantage of increasing efficiency.
