Abstract:

Breakdown and explosive plasma formation on electrodes are basic processes in pulsed power discharges. Despite their fundamental importance, the details of cathode spot formation have not been well understood. Breakdown in a vacuum diode is initiated by field emitted electrons. Besides joule heating of the emitting spot, the electrons also ionize desorbed gas layers. These ions fall back to the cathode, heating the surface of the electron emitting spot. Ion surface heating is initially orders of magnitude larger than joule heating.
