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...

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...

Synthesis of Carbon Nanofibers by a Glow-arc Discharge

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...

Glow Discharge Depth Profiling a Powerful Analytical Technique in Surface Engineering (TECHNICAL NOTE)

A variety of analytical techniques have been developed and employed to characterize the surfaces, subsurfaces and interfaces of surface engineering systems. They provide important information for quality control, process optimization and further development. Since the mid 1980's, glow discharge spectrometry (GDS) has emerged as an important and versatile technique for rapid depth profiling anal...
