| 摘 要： | 在详细分析快波结构中的束波互作用基础上,采用2.5维PIC粒子模拟软件设计了一种回旋器件。该器件采用摇摆器形成回旋电子束,并采用强耦合方式和优化的互作用段长度，在束压250 kV、束流200 A、脉宽1 ns的电子束驱动下，模拟获得了峰值功率7 MW、频率38.5 GHz的微波短脉冲输出，峰值功率转换效率达到14%。其峰值输出功率与束脉宽之间的平方关系符合超辐射效应的特征。

| Abstract: | A cyclotron was designed using the 2.5 dimensional particle simulation code KARAT in the paper.Transverse momentum of the electrons was imparted by a kicker.By using intense coupling and optimized length of the interaction space,the device could generate microwave pulse with a peak power of 7 MW,an operating frequency of 38.5 GHz with the diving electron beam of 250 kV,200 A and 1 ns.The peak power conversion reached 14%.The peak power had a square relationship with the beam pulse width during certain range,which was in accordance with the character of superradiance. |
