摘要：

The micro-pulse electron gun (MPG) is a new type of cold cathode microwave electron gun that can produce short duration, high current density electron beams The principle of MPG is multipactor (or multipacting). In this paper, our proof-of-principle experiment on a MPG is presented. One kind of Cu-Al-Mg alloy has been used as the cold cathode. A current with the density up to 100mA/cm(2) was observed. The results agree well with the analytical calculation and the computer simulation. The experiment verifies both the analytical theory and the computer code, and prepares the way for the higher current density approach.
