Runaway electrons during subnanosecond breakdowns in high‐pressure gases

open access: yesHigh Voltage, Volume 1, Issue 4, Page 181-191, December 2016., 2016
The parameters of runaway electrons produced in nanosecond high‐voltage discharges in different gases (air, nitrogen, sulphur hexafluoride, krypton, argon, methane, neon, hydrogen, helium) at atmospheric and higher pressure were studied. An optical analysis was also performed to investigate the ionisation dynamics in diffuse discharges in nitrogen and ...

Comparison between electropositive and electronegative cold atmospheric‐pressure plasmas: a modelling study

open access: yesHigh Voltage, Volume 1, Issue 2, Page 81-85, July 2016., 2016
Cold atmospheric‐pressure He + N2 and He + O2 plasmas are chosen as the representatives for electropositive and electronegative plasmas, of which the discharge characteristics are studied and then compared to each other by fluid models. As the increase of the impurity (N2 or O2) fraction from 0 to 10%, for He + N2 plasmas the electron density and ion ...
