Microwave Diagnostics for Investigation of Long Spark and Artificial Charged Aerosol Cloud

Presented is the project of the microwave diagnostics, intended for measuring the absolute value and dynamics of space-averaged conductivity of plasma in the streamer zone and the sheath of a long spark and plasma inside the artificial charged aerosol cloud during a discharge process. The first results of artificial charged aerosol cloud discharges investigation with use of the microwave diagnostics are obtained. By weakening the probing microwave radiation was measured absolute value and dynamics of space-averaged electron density in the cloud during discharges initiated by grounded metal ball.
