Research Abstract |
Electric field distributions in repetitive nanosecond-pulsed discharges, generated at 0.3 atm hydrogen environment are studied. Results revealed that the initiation of net charge accumulation near the cathode occurs very rapidly with the drastic change of the electric field distribution. Furthermore, the feasibility of electric field measurement based on E-CRS has been demonstrated for the first time in a nitrogen-containing gas at atmospheric or higher pressure, including open air.
