摘要
会切(CUSP)磁场是产生大回旋空心CUSP电子注的关键,该文分别对CUSP磁场中双曲正切模式和Moster-Molnar模型进行探讨,通过理论分析和数值模拟,建立适合于大回旋器件用CUSP磁场的物理模型;并对CUSP磁场设计中的影响因数进行探讨;同时探讨了CUSP磁场与大回旋空心CUSP电子枪的关系,结果表明:改变CUSP磁场的阴极区磁场的变化对设计低速度零散、低纹波、高速度比值α的轴向环绕大轨迹CUSP电子枪有较大的影响。
The CUSP magnetic field is key coming into brings the large orbit hollow CUSP electronic beam. In this article, the hyperbolic tangent model and the Moster-molnar model is discussed. The physical models of the cusp magnetic field is built up to fit in gyro-TWT amplifier, and carried on theory analyzing and numerical simula- tion of magnetic field of CUSP. the relations of the large orbit hollow CUSP electron guns and the CUSP magnetic field are researched at the same time. The results of numerical analysis show changing the cathode magnetic field of the cusp has very important effect on the performance of a cusp gun, such as designed to generate an axis encircling the large orbit CUSP electron gun with low-velocity spread, small beam ripple and high speed ratio.
