Study on the Ionic Bombardment in a Glow Discharge Lamp
The surface of copper alloys was studied by means of a scanning electron microscope after having been sputtered by a glow discharge source under typical conditions for spectrochemical analysis. The surface topography developed during the process of sputtering gave the following two results: It would appear that the energy spread of the bombarding ions is small and the variation in the angles of...
متن کاملActive 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...
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 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 کاملThe Stewart-Thompson Theory applied to the Glow Discharge
The surface topography developed on copper-based and ferrous alloys after being sputtered in a glow discharge lamp and in an ion microprobe was studied by means of a scanning electron microscope and an ion microprobe mass analyser. The observed surface topography, though obtained under completely different conditions, was found to be similar to that predicted by the theory of Stewart and Thompson.
