【摘要】 新一代宽带、高增益、大功率回旋行波管需要新型的电了注,而大回旋CUSP电子注为其实现提供了可能。本文对大回旋CUSP电子注进行系统理论分析,建立了大回旋CUSP电子注的物理模型,理论分析基础上进行了大量数值计算和模拟优化,并对大回旋GUSP申子枪设计中的影响因素进行探讨。完成了CUSP 电子枪的设计,设计出一支低速度零散、高速度比、低纹波,适用与高次谐波的高功率(54kV,2．7A)CUSP电子枪。更多还原

【Abstract】 The new generation gyro-TWT of broad band, high gain, and high power will ask new type electron beam, but the large orbit gyrotron(LOG)GUSP electron beam can be used to it. In this paper, it analyzed to the large orbit gyrotron(LOG) GUSP electron beam, The physical models of the cusp electron beam was built up, and carried on theory analyzing, to discuss effect on the factor in design for the large orbit gyrotron(LOG) Gusp electron gun. A CUSP gun, designed to generate an axis encircling beam with low-velocity spread and small beam ripple for high-harmonic high-power (52kV, 2.7A) operation in gyrotrons, was successfully designed.更多还原
