Abstract
A method for stabilizing the prebreakdown state of vacuum gaps, based on the use of an anode made of a material with high specific resistance, has been proposed and implemented on an experimental stand. Traces of prebreakdown phenomena on the surface of cathodes, which usually lead to a vacuum spark and self-destruction, were identified and a preliminary study was conducted. This technique will allow for further expanding the understanding of the nature of vacuum breakdown and electroplastic phenomena in critically strong electric fields with a strength of over 1 MV/cm. It is proposed to use prebreakdown electrostatic treatment of the surface of metals and semiconductors to study the possibility of obtaining effective cold electron emitters.
期刊介绍：
Instruments and Experimental Techniques is an international peer reviewed journal that publishes reviews describing advanced methods for physical measurements and techniques and original articles that present techniques for physical measurements, principles of operation, design, methods of application, and analysis of the operation of physical instruments used in all fields of experimental physics and when conducting measurements using physical methods and instruments in astronomy, natural sciences, chemistry, biology, medicine, and ecology.
