THE ROLE OF DIELECTRIC NOZZLE ON X-RADIATION OF RUNAWAY ELECTRONS DURING HIGH VOLTAGE BREAKDOWN

Present article is dedicated by detection of the role of dielectric nozzle at the potential electrode on Xradiation dose near cathode and anode during formation of nanosecond pulsed discharge in high pressure air. It is shown, that heterogeneity of electrical field and the presence of porcelain cap at the rod with small radius of curvature influents on registration and X-radiation area in atmospheric air. The pressure rise in gas gap reduces to X-radiation near cathode with big radius of curvature in the absence of acrylic resin cap on it.
