Keywords： permanent magnet

Firstly,an X-band relativistic backward wave oscillator with a low guiding magnetic field is simulated,whose output microwave power is 520 MW.Then,an experiment is carried out on an accelerator to investigate a relativistic backward wave oscillator with a permanent magnetic field whose strength is 0.46 T.When the energy of the electron is 630 keV and the current of the electron beam is 6.7 kA,a 15 ns width pulsed microwave with 510 MW output power at 8.0 GHz microwave frequency is achieved.
