回旋管双阳极磁控注入电子枪分析与数值计算

Analysis and Numerical Calculation of a Double Anode Magnetron Injection Gun for Gyrotron

根据回旋管对电子枪的要求,考虑相对论效应和空间电荷效应,编制了一套大型的计算程序。利用计算机辅助设计,计算出了电极形状、电子轨迹与电子注参量。计算表明,这种电子枪具有速度零散小、层流性较好、体积小等优点。

According to the requirements for the gyrotrons, the relativistic effect and the space charge effect were taken into account, a set of large program is developed for CAD. The shape of electrodes, electron trajectory and electron beam parameters are given by the computer adided design. The electron gun has some advantage such as small velocity spread , good laminar flow and small volume etc.
