Research on Multi-pulsed High Intense Electron Vacuum Diode

Abstract: There are some differences between the single pulsed vacuum diode and the multi-pulsed vacuum diode. When vacuum diode is working under multi-pulsed mode, cathode plasma changes the designed condition inevitably. Formulas are presented in the paper to describe the vacuum while it is working under multi-pulsed mode. Simulation is used to describe cathode plasma explosion behavior. A column explosion mode is adopted in the paper while simulating cathode emitting. Experiments are also undertaken to study the characteristics of electron beams generated by a double pulsed intense electron diode with velvet cathode. When the diode pulsed voltages are 700kV, the beams' brightness is better than 1×108A/(m.rad)2 and the two beams' envelope changes little during beams' extraction process.
