Abstract

Abstract

The repetitive explosive emission cathode (EEC) is the key component of high power diode for generating repetitive electron beams. The emission mechanisms of the cathodes triggered by whiskers and flashover are introduced in detail. Factors that limit the repetition rate are analyzed. Development and characteristics of some EECs are summarized. LaB6 is proposed as EEC material and a novel configuration of cold cathodes (metal-spoked ceramic compound cathode) is designed.
