LOW PRESSURE DISCHARGE INDUCED BY MICROWAVES WITH STOCHASTICALLY JUMPING PHASE

We study the gas discharge, initiated by microwave radiation with stochastically jumping phase (MWJP) in a coaxial waveguide in the optimal mode of the beam-plasma generator. In this paper we experimentally examine optical characteristics of the discharge plasma in a wide range of air pressure. The conditions of a microwave discharge ignition, its stable maintenance in air by MWJP, and the pressure range at which required power is minimal are found.
