Microwave capillary torch as a means for modifying the electrophysical characteristics of metal surfaces

An experiment layout based on a pulsed capillary microwave torch and making it possible to excite an explosive emission microplasma on a metal surface in open air is implemented for the first time. It is shown that a microrelief in the form of micron-size microcraters forms on the initially smooth surface under the action of microsparks. As a result, the maximum secondary electron emission yield σ_max decreases from ～2 for the untreated surface to ～0.4 for the rough treated surface and remains low for a long time when exposed to atmospheric air.
