Glow discharge - Wikipedia
A glow discharge is a plasma formed by the passage of electric current through a gas. It is often created by applying a voltage between two electrodes in a glass tube containing a low-pressure gas. When the voltage exceeds a value called the striking voltage , the gas ionization becomes self-sustaining, and the tube glows with a colored light.

Electric glow discharge is a type of plasma formed by passing a current at 100 V to several kV through a gas, usually argon or another noble gas. It is found in products such as fluorescent lights and plasma-screen televisions, and is used in plasma physics and analytical chemistry, and has been proposed as an
Electric discharge in gases - Wikipedia
Electric discharge in gases occurs when electric current flows through a gaseous medium due to ionization of the gas. Depending on several factors, the discharge may radiate visible light. The properties of electric discharges in gases are studied in connection with design of lighting sources and in the design of high voltage electrical equipment.
Glow Discharge - an overview | ScienceDirect Topics
According to more descriptive physical definition, a glow discharge is the self-sustained continuous directly current (DC) discharge having a cold cathode that emits electrons as a result of secondary emission mostly induced by positive ions [16].
Glows, arcs, ohmic discharges: An electrode-centered review on ...
2024年7月19日 · In this review, glow discharges are defined by their individual electron emission mechanism such as secondary electron emission by photons and primary ions, and arcs by their respective collective mechanism such as thermionic or explosive electron emission.
88.03 -- Glow discharge - UC Santa Barbara
Glow discharge is the formation of a plasma by the electrical breakdown of a gas. Normally, gases are insulators. Because of cosmic rays or other natural background radiation, a volume of gas contains a few randomly generated electrons.
The Measurement and Analysis of Electric Fields in Glow Discharge ...
1994年1月1日 · This article is a review of recent work that used optical diagnostics to study electric fields in glow discharge plasmas. Alternative methods for measuring electric fields in plasmas include electron beam deflection ( Warren, 1955 ) and electrostatic probes ( Hershkowitz and Cho, 1988 ).
Characterization of argon direct-current glow discharge with a ...
2014年9月10日 · Different geometries of electrode and different types of gas were employed to characterize the DC glow discharge in laboratory. A DC microhollow cathode discharge (MHCD) in atmospheric...

Electric glow discharge is a type of plasma formed by passing a current at 100 V to several kV through a gas, usually argon or another noble gas. It is found in products such as fluorescent lights and plasma-screen televisions, and is used in plasma physics and analytical chemistry.
electrical discharge plasmas are not in thermal equilibrium, since Te >>Tg and Te >Ti >Tg [6]. The two most common types of electrically induced plasmas are the direct-current glow discharge, and the radio-frequency discharge, where a radio-frequency electric
