Abstract :
Multiple beam klystron (MBK) was rapidly developed in recent 20 years because of its unique excellence. Impregnated cathode unit (ICU) with high electronic emission density is one of key technology for manufacture of multi-beam klystron. In this paper, some experiment was made in process of preparing MBK cathode unit. Also several skills were applied to make impregnated cathode unit. The ICUs used in MBK had achieved good result, not only the emission density was satisfied with the demand of device, the problem of electron gun breakdown was overcome also, and the reliability of MBK was improved finally.
