Glow discharge impact upon changes in Ni3Fe dislocation structure

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...

Dislocation-density changes upon poling of polycrystalline BaTiO3

We report evidence for a significant increase of bulk dislocation density upon poling of polycrystalline BaTiO3. The synchrotron high-resolution x-ray-diffraction measurements yield a dislocation density on the order of 10/cm and an associated strain-energy increase of about 20 kJ/m. This implies that the application of an external poling field generates defects in the structure and increases t...

Observations of a structure-forming instability in a dc-glow-discharge dusty plasma.

By adjusting the anode current and axial magnetic strength of a dc-glow-discharge dusty plasma, we have found plasma and dust conditions conducive to dusty plasma structurization, similar to the one discussed theoretically by Morfill and Tsytovich [Plasma Phys. Rep. 26, 682 (2000)]. The structurization instability leads to the formation of a pattern where the dust suspension transforms into alt...
