Paper Abstract

Nowadays of microwave (MW) gas discharge applications are actively investigated in different areas of science and technology. Greatest optimism in applications is connected with streamer discharge forms. A possibility of streamer form discharge applications is determined by their specific features. An efficiency of energy absorption is close to 100% in this discharge. The discharge develops in a form of a spatial structure consisting of streamer element interconnected. They explode at reaching of electrodynamic resonance. The discharge structure represents a net of thin plasma channels. Gas temperature reaches several thousands of Kelvin degrees inside them. A typical time of energy absorption by separate plasma channels is several units of microseconds. A velocity of a streamer growth is about of - 106 cm/s. Main physical mechanisms determining features of MW discharges have been qualitatively clarified nowadays. But quantitative investigations of discharge creation processes are required for effective applications of these discharges. For this purpose equipment, which has characteristics allowing detecting processes with resolution time in microsecond and submicrosecond range, is necessary. In this work we represent investigation results of streamer MW discharge in air: initial development stage, developed stage of a volumetric discharge and development of the discharge on a surface of radiotransparent dielectric material. Investigations have been realized with a help of K011 image converter camera.
