Behavior of arc spots was investigated in detail using a nanostructured tungsten specimen with different thicknesses of the nanostructured layer. From the observation using a fast framing camera, it was found that the velocity of the arc spots signif

Laser-induced arc was initiated on a nanostructured “fuzz” tungsten cathode with simultaneous exposure to a stationary helium (He) plasma. Arc spots moved randomly and eroded almost all the surface area. The diameter of each arc spot was measured

A model is proposed for investigation of the ionization processes in a plasma jet emitted by a cathode spot cell of W-fuzz cathodes. It was shown that the introduction of helium atoms and the associated change in the morphology of the surface of the

Self-consistent modeling of anode heating by a vacuum arc during 50 Hz half-wave of a current with contact opening speed of 1 m/s is carried out. As a result of the simulation, the heating of the anode to the temperature at which the metal vapor begi

Experimental data on the effect of the thickness of a nanostructured layer present on the surface of a tungsten cathode on its arcing properties have been analyzed. It has been shown that if the nanostructured layer is not completely destroyed as a r

Runaway electrons accelerated in the electric field of a pulsed discharge may substantially change the discharge properties. The existence of this acceleration mechanism is indicated by the x-rays emitted from the discharge and by the increasing prop

Kinetic numerical simulation of plasma near the cathode spot (CS) was performed. Two types of possible solutions for the self-sustained CS on copper cathode were found. The firs type of solutions is valid for quasi-stationary spot with radius of abou

The parameters of the cathode spot plasma produced by explosive electron emission pulses have been estimated from the critical state properties for various materials. The kinetic energy of the cathode plasma flare has been estimated as 100 Tcr, where
