Diffuse Glow

Streak photography has been used to supplement the earlier shutter photo. graphic investigation of Doran and Meyer (1967) using the same coaxial cable discharge circuit. Additional information has also been obtained from measurement of the potential distribution between the electrodes at two stages in the spark development. Redistribution of space charge is shown to give rise firstly to a transient diffuse glow discharge that has a close similarity with a normal d.c. glow discharge. It has also been shown that, even while the diffuse glow discharge expands, a partial constriction occurs in which most of the current flows along a narrow axial column. The resulting maximum in electron density eventually causes a rapid increase in dissociation of molecular hydrogen on the axis of the discharge brought about by a rise in the gas temperature. Owing to its greater electrical conductivity this axial column soon carries the entire current and the discharge becomes filamentary though still being maintained by a high cathode fall field, which exists until a sudden change in the cathode mechanism gives rise to the low voltage arc channel. Both the filamentary glow and arc columns are observed to expand according to an r cc ti law.

Abstract We report the results of optical emission spectroscopy measurements of rotational Trot and translational (gas) temperature of deuterium molecules. The light source was a low-voltage high-pressure hollow cathode (HC) glow discharge with titanium cathode operated in deuterium. The rotational temperature of excited electronic states of D2 was determined from the intensity distribution in the rotational structure of Q-branches of the two Fulcher-α diagonal bands: [ν′ = ν″ = 2] and [ν′ =ν″ = 3]. The population of the excited energy levels, determined from relative line intensities, was used to derive the radial distributions of the temperature of the excited and the ground state of the deuterium molecule.

A low-voltage low-pressure glow discharge with a hollow cathode is considered. The discharge is ignited in a reflective discharge system with two symmetrical peripheral discharge chambers, with a common extended hollow cathode at forevacuum. Plasma parameters were determined, admissible diameter of the plasma column in a hollow cathode. It is shown that there is no electric double layer in the region of the output aperture of the cathode cavity.

Dark Decay

Amorphous selenium is often used as the basic photoreceptor material in xerography in the form of a layer on an aluminum substrate. It is found that the dark decay rate of charge on the selenium surface can be reduced by the presence of a thin aluminum oxide film between the selenium and the substrate metal. In this study, different methods were explored for forming this film, including direct thermal oxidation and various glow-discharge methods. It was found that with thermal oxidation and low voltage glow discharge, the film thicknesses were limited to about 200 Å (1 Å = 10−10 m). However, with dc reactive sputtering, aluminum oxide films with thicknesses of more than 2000 Å could be prepared. Evaluation of the films, with the selenium layer present, indicated that the low voltage glow-discharge and direct thermal oxidation methods gave the best results xerographically.
