Abstract

Abstract

The dynamics behaviors of high power long pulse foilless diode were analyzed on the basis of diode design theory. The result indicated that the back flowing electrons must be cut off, and can not bombard the dielectric surface and the wall of the foil-less diode tube. In the experiment on the diode used on a long pulse linear transformer driver, through shielding design for the diode’s cathode structure, a long pulse high power annular electron beam with power up to 5 GW was obtained with repetition frequency of 25 Hz and energy transmission efficiency over 95%.
