Study of Current - Voltage Characteristics of Normal and Abnormal Glow Discharge in Air at Low Pressures

Tikrit Journal of Pure Science, 2019
In the present study experimental measurements have been carried out to investigate the variation of air discharge voltage (V) and current (I) as a function of working pressure (p), in the ranges (300-500 V), (2-15 mA) and (0.09-0.13 Torr) respectively.

A series of plasma innovation technologies by the double glow discharge phenomenon

AIP Advances, 2023
In order to break the limitation of plasma nitriding technology, which can only be applied to a few non-metallic gaseous elements, the “double glow discharge phenomenon” was defined and then the “double glow plasma surface metallurgy technology” was ...

Control and Stabilization of Centimeter Scale Glow Discharge in Ambient Air Using Pulse-Width Modulation

IEEE Access, 2020
Re-pulsing glow discharges in atmospheric-pressure air were experimentally investigated using a push-pull generator with pulse-width modulation. Discharges were ignited as a spark-glow discharge sequence and sustained in a glow regime after ignition in a

Spatial characterization of pressure-based plasma regimes in a radiofrequency glow discharge by using optical emission spectroscopy [PDF]

, 2011
International audienceA new experimental set-up has been developed in order to perform spatially resolved measurements of the optical emission in a radiofrequency glow discharge (rf-GD). The emitted radiation is not only detected through an end-on window

Theoretical Study on Characteristics of Glow Discharged Neon Gas and Its Interaction With Terahertz Waves

Frontiers in Physics, 2021
Discharge gases have been used to detect terahertz (THz) waves, however, there are few relevant theoretical studies. The neon glow discharge model is established by COMSOL Multiphysics software, the characteristics of glow discharged neon and the ...
