Graphite formation in abnormal glow discharge

Radiation 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...

Active Noise Control Using Glow Discharge

First-day spacecraft failures frequently occur as a result of the loads experienced during launch into orbit. These loads include structural vibrations transmitted at points of structural contact, and structural-acoustic vibrations created by the excitation of the payload fairing cavity. Structural control techniques, using piezoelectric actuators, have previously been studied as cost-effective...

Effects of Ion Bombardment on Carbon Nanotube Formation in Strongly Magnetized Glow-Discharge Plasmas

Influence of Argon Gas Concentration in N2-Ar Plasma for the Nitridation of Si in Abnormal Glow Discharge

Nitriding of p-type Si samples by pulsed DC glow discharge is carried out for different Ar concentrations (30% to 90%) in nitrogen-argon plasma whereas the other parameters like pressure (2 mbar), treatment time (4 hr) and power (175 W) are kept constant. The phase identification, crystal structure, crystallinity, chemical composition, surface morphology and topography of the nitrided layer are...

Recombination Lasers in a Flowing Negative Glow Discharge

A fast gas flow through a negative glow plasma creates an afterglow region where supercooled electrons are separated from energetic beam electrons to produce a population inversion by collisional recombination. We report spatially-resolved electron temperature measurements of the afterglow plasma showing electron temperatures in the range of 750-1100 K under steady-state conditions. A 4 em long...
