ABSTRACT
The effect of full voltage on the efficiency of the pulsed conditioning of electrodes in a vacuum is assessed. The efficiency of optimal conditioning modes, estimated from the quality of the cathode surface relative to gaps of centimeter length and long-acting voltage, increases by more than two orders of magnitude when the pulse duration and interelectrode gap are reduced. An increase of up to one order of magnitude is achieved by reducing the gap width to micron sizes during conditioning. The efficiency increases by a factor of as much as 30 by reducing the pulse duration and raising the optimal regime’s pulse power.
