Dust particle charging in DC glow discharge plasma
Dust particles charging in a stratified positive column of a low-pressure DC glow discharge was investigated theoretically. The presented model consists of (i) previously developed 1D selfconsistent model for discharge parameters on the tube axis; (ii) ambipolar approximation for radial electric potential distribution and the assumption that the electron energy distribution function in radial d...
متن کاملThe Influence of External Magnetic Field on the Radiation Emitted by Negative Glow of a Dc Glow Discharge
This work represents a first attempt to use the cylindrical coaxial magnetron discharge (CCMD), obtained in air, as a light source. The main purpose was to realize a high efficiency of conversion of electric power to visible light and to optimize the operating conditions to minimize the cost of the light source, employing a cheap gas (air) and moderate voltage in the range of several hundreds v...
متن کاملGeneration of Plasma Induced Flow Actuation by DC Glow-like Discharge in a Supersonic Flow
Plasma induced flow field modification is studied experimentally using non-equilibrium DC surface discharge in a Mach 3 supersonic flow. An array of small pin electrodes (φ = 3/32”) is used in streamwise plasma discharge configuration. The schlieren imaging shows that an oblique shock can be obtained with a volumetric glow discharge on the cathode with a relatively low current (as low as 50 mA)...
متن کاملRadiation Produced by Glow Discharge in Deuterium
Radiation produced by low-voltage discharge in a gas containing deuterium was measured using a Geiger counter located within the apparatus. This radiation was found to consist of energetic particles that were produced only when the voltage was above a critical value. In addition, the emission was very sensitive to the presence of oxygen in the gas. In the presence of the required conditions, em...
متن کاملDouble Langmuir probe measurement of plasma parameters in a dc glow discharge
In this paper, plasma main characteristics such as electron mean temperature, electron number density, and oscillation frequency have been measured experimentally using the double Langmuir probe diagnostic system. In our experiment, the plasma was generated by applying the low pressure dc glow discharge in several common gases. The experimental results indicated the highest plasma density and o...
