A generalized formula for electron emission current as a function of temperature, field, and electron work function in a metal–dielectric system has been derived with regard to the quantum nature of image forces. For free electrons, the Fermi–Dir

It has been 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). The physical processes involved in a

2020 29th International Symposium on Discharges and Electrical Insulation in Vacuum (ISDEIV).
An experimental and theoretical study of the content of deuterium ions in the arc discharge plasma was performed for deuterated zirconium cathodes. It was found experimentally that in a high-current arc mode with a current pulse duration of several m

A two-dimensional kinetic simulation of the expansion of the current-carrying plasma of the cathode spot of a vacuum arc is carried out. The modeling was performed by Particle-in-Cell and Direct Simulation Monte Carlo methods. The processes of ioniza

For electrodes exposed to radio frequency electromagnetic fields, it is shown that an increase in electrode temperature on the nanosecond time scale increases the time required for an electrode surface microprotrusion to be heated to the critical tem

The investigation of the He-induced W “fuzz” electrical properties was carried out. For the research, an automated experimental setup was designed. The setup was based on a vacuum chamber operated under high vacuum conditions (~ 10−7 Pa). The v

We have studied the mass and charge composition of an ion beam extracted from the plasma of a vacuum arc with a zirconium deuteride cathode for various durations of the arc current pulse (half width at half amplitude) of 2, 4, 7, and 17 μs. It has b
The paper considers the dynamics of the plasma generated by the explosive-emission cells of the cathode spot of a vacuum arc in a magnetic field. It is shown that the expansion of the (high-density) plasma in a transverse magnetic field may cause asy

Graphite cathode surface erosion in the pulseless negative corona discharge in air is studied in the point-plane electrode configuration at a pressure of 0.3–1 atm. The formation of erosion craters in the form of orderly arranged erosion cells shap
