摘要: 根据回旋管对电子枪的要求，采用综合法和分析法设计了该单阳极磁控注入电子枪。编制了一套大型的计算程序，利用计算机辅助设计，给出了电极形状、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、体积小等特点。该枪已用于制管实验中。由热测实验表明，它具有明显的优点，并获得了127kW的峰值功率和超过10%的效率。Abstract: A single anode magnetron injection electron gun is designed and calculated according to the requirements of gyrotrons with a presented method, which combines synthesis with analysis. A set of computer program has been developed. The electrode shapes, electron trajectory and electron beam parameters are also given with the computer aided design. The electron gun has the characteristics such as small velocity spread, good laminar flow and small volume etc. This gun was applied in the experiment, which shows a gun designed with the method has obtained 127kＷ peak power with over 10% efficiency.
