| 摘 要： | 首先通过粒子模拟设计了一个X波段的低磁场返波管振荡器,得到功率为520MW、频率为7.9GHz的微波输出;然后根据模拟结果设计加工了一个磁场强度为0.46T的小型化永磁磁体;最后在加速器上对永磁包装返波管振荡器进行了实验研究。当电子能量为630keV、束流约为6.7kA时,返波管振荡器得到频率为8.0GHz、功率为510MW、脉冲半高宽约15ns的微波输出。

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