本文简要地叙述了迴旋管绝热磁控注入枪中的电子运动,提出在阴极附近引入一个温度限制发射的等效二极管的概念,并从对这个二极管中电子流的分析、双圆筒电极间的场分布和绝热理论出发,推导出由枪电极尺寸和电磁参量确定的电子注横向能量的计算公式 根据这个公式,可方便、迅速、准确地进行枪的主要参量的设计,或由实测参量判断整管中电子注的运动状态。 关于阴极电场的计算,曾对许多实际的绝热磁控枪用电子计算机进行数值计算分析对比,误差小于5％,与文献[1]的计算机计算结果是一致的。简化模型方法已经实验验证,电子注横向能量的计算值与实验结果,基本吻合。
This paper briefly describes the electron movement in a gyrotron adiabatic magnetron injection gun and proposes the concept of introducing a temperature-limiting equivalent diode near the cathode. From the analysis of the electron flow in this diode, Field distribution and adiabatic theory, the formula for calculating transverse energy of electron injection determined by gun electrode size and electromagnetic parameter is deduced. According to this formula, the design of the main parameters of the gun can be conveniently, quickly and accurately, or it can be judged from the measured parameters Tube electronic injection exercise state. On the calculation of the cathode electric field, many practical computer numerical control adiabatic magnetron gun comparison, the error is less than 5%, and the literature [1] is consistent with the results of the computer. The simplified model method has been experimentally verified that the calculated value of the transverse energy of the electron beam is in good agreement with the experimental result.
