Experiment study of long- time and stable operation of repetitive pulsed and intense current electron- beam source

The components, main characters and operation principles of the repetitive pulsed and intense current electron- beam accelerator which is based on pulsed transformer are introduced in this paper, on this equipment, the experiment study of long- time and stable operation of electron- beam source are carried out, and the results reach or partially exceed the designed parameters. While the repetition rate is 100 Hz, the pulsed transformer can deliver high voltage pulse of 1.15 MV, the intense current electron- beam diode can operate steadily as long as 5 s, its output beam voltage exceeds 800 kV, beam current exceeds 7 kA, pulse width is 45 ns, and the emission density of cathode is near 10 kA/cm2. A quasi- periodic slow wave structure device is studied using this electron- beam source, the r
