摘要
提出在热阴极微波电子枪的设计中可以通过缩短腔长减小电子反轰功率，并通过模拟计算详细研究了腔长对电子反奎及枪出口束流品质的影响．
In this paper the back bombardment of electrons in rf thermionic guns is studied for cavity design. We put forward that shortening the length of cavities can decrease the back bombardment power sharply and. obtain electron bunches. with better qualities. The simulation results of back bombardment power and electron beam parameters at exit of rf guns with various cavity lengths are presented. The idea has been.adopted in the multi-cavity rf thermionic gun for BFEL.
