4. Thermal equilibrium for a microscopic protrusion of a surface subjected to high voltage
The cathode, like any metal subjected to a strong electric field, emits electrons (§ 1 ). This section details the mechanisms governing the thermal equilibrium of a protrusion on the cathode surface, which can lead to its "explosion" (vaporization or sublimation) induced by cathode spots, sometimes even harmful to the electrode conditioning phases.
The steady-state equilibrium heat equation is presented for the...
