    Experimental study of energy balance for an electro-rocket thruster with an anode layer and power up to 1000 W

    Experimental results and a procedure for determining the total energy balance for single-stage thrusters with azimuth electron drift are presented. A single-stage thruster with an anode layer (TAL) with power ...

    Thermionic valve effect and cathode crater rhythm in a low-voltage cold-cathode vacuum arc

    A vacuum arc with a cold cathode burns rhythmically. The period of the rhythm is determined by a thermionic valve effect which occurs between the hot crater and the cold cathode as a result of the brief retent...

    Formation of a cathode crater in a low-voltage cold-cathode vacuum arc

    The cathode crater in a low-voltage cold-cathode vacuum arc is planar. The area of the crater and the density of the current flowing through it depend on the thermal and electrical properties of the cathode me...
