Özet

The stable de air cold plasma is investigated experimentally functions of pressure p (8-760 Torr), electrode gaps d (50-250 mu m), and diameters (9-22 mm) of the cathode areas in the gas discharge electronic devices (GDED) with nanoporous zeolite cathode (ZC). It is found that the current density and plasma emission (PE) intensity increase if the amplitude of the applied voltage reaches given threshold. Moreover, uniform PE inside the ZCs develops from the surface and can be generated in air up to atmospheric pressure (AP). The effect of various diameter of the ZC area on the gas breakdown is also considered. It is shown that breakdown voltage U-B is reduced significantly for the larger diameters of the ZC area. Because of the very small d in our GDED, the behavior of charged particles in the electric field is described with the de Townsend breakdown theory, depending upon the pressure range.
