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

This paper discusses the issues of a possible change of the type of cathode attachment of high-current vacuum arcs (HCVA) with an average cathode current density of more than 105 A/cm2. This type of HCVA is used as pumping plasma gun in experiments w

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

The dynamics of phase changes in the material of a copper cathode during the explosion of a microprotrusion on its surface under the action of the explosive electron emission current has been numerically simulated. Numerical data have been obtained t

A two-dimensional axisymmetric model has been developed to describe the formation of liquid-metal jet and the droplet pinch-off. These processes occur during the extrusion of the melt from the crater by the pressure of the cathode spot plasma of a va

Transition of field-emitted electrons into the runaway mode is investigated in the region of enhanced electric field determined by the configuration of a microtip on a cathode for various gas media composition and pressure. The research is done using

2016 27th International Symposium on Discharges and Electrical Insulation in Vacuum (ISDEIV).
A semiempirical hydrodynamic model based on the cellular structure of the cathode spot of a vacuum arc has been developed to describe the formation of a microcrater on the cathode and the initial stage of the formation of liquid-metal jets. The model

This paper considers the 'current techniques' for field emission investigations of the parameters of BCS-like superconductors, which are based on observing the change in field emission current upon the superconducting-to-normal (or reverse) phase tra
