摘要
介绍了用于１＋１／２射频腔中的ＬａＢ＿６热阴极电子枪的结构，通过分析电子枪阴极的热平衡关系和高温、强射频场条件下的阴极电流发射情况，给出了ＬａＢ＿６热阴极电子枪的热平衡和发射电流的关系曲线，并对阴极稳定性问题进行了仔细研究。
In this paper, we briefly introduce the structure of the LaB_6 thermionic cathode for 1 + 1/2 RF cavity. The heating balance power of thermionic cathode and the emission status of electrons from the high temperature in high RF field have been analyzed.The electron beam current density of LaB_6 versus cathode heating power have been given. Finally,problems of stability of the LaB_6 cathode have been also studied.
