TL;DR: In this paper, the authors investigated whether explosive electron emission may be the initiating mechanism of vacuum breakdown in the accelerating structures of TeV linear electron-positron colliders (Compact Linear Collider).

Numerical Simulation of Plasma Near the Cathode Spot of Vacuum Arc
TL;DR: In this paper, two types of possible solutions for the self-sustained cathode spot on copper cathode were found, and the firs type of solutions are valid for quasi-stationary spot with radius of about $100~\mu \text{m}$. Stationary solution in this case is possible with cathode temperature 4.2-4.5 kK, current density $\sim 10^{6}$ A/cm2, and applied voltage 20−25 V.

Explosive Electron Emission Ignition at the “W-Fuzz” Surface Under Plasma Power Load
TL;DR: In this article, the authors analyzed the plasma action onto a nanostructured W-fuzz surface and found that such a fine structure of the surface promotes a local ecton-process ignition by plasma action.

Transition in velocity and grouping of arc spot on different nanostructured tungsten electrodes
TL;DR: In this article, the behavior of arc spots was investigated in detail using a nanostructured tungsten specimen with different thicknesses of the nanostructure layer, and it was found that the velocity of the arc spots significantly altered as passing the boundary of the two layers.

On the anode potential fall in a vacuum arc: PIC simulation
TL;DR: In this paper, a particle-in-cell (PIC) method was used to simulate the interaction of plasma generated by a vacuum arc with the anode surface, and the potential fall was found to be negative even at high electron drift velocities.
