Influence of Contamination and Structural Defects
a microdischarge between the electrode and an oncoming particle which initiates breakdown between the electrodes in vacuum or gas
the collision of a high-velocity particle with an electrode accompanied by the emission of vapor and liquid electrode and particle fragments and plasma structures in vacuum
collisions of particles with electrodes that alter electrode microrelief, thereby producing field amplification centers
single particles and particle bridges produced when particles enter the strong field region, which distort the field distribution
impurity particles in insulating liquids, which influence electrohydrodynamic processes during long-term voltage exposure.
