Transition from Townsend to glow discharge: subcritical, mixed, or supercritical characteristics.
The transition from Townsend to glow discharge is investigated numerically in one space dimension in full parameter space within the classical model: with electrons and positive ions drifting in the local electric field, impact ionization by electrons (alpha process), secondary electron emission from the cathode (gamma process) and space charge effects. We also perform a systematic analytical s...
متن کاملDependence of the transition from Townsend to glow discharge on secondary emission.
, (1991)]]. Sijacić and Ebert stated that this transition strongly depends on secondary emission gamma from the cathode. We show here that the earlier results of von Engel and Raizer on the small current expansion about the Townsend limit actually are the limit of small gamma of the Sijacić and Ebert expression, and that for larger gamma the old and the Sijacić and Ebert new results vary by no ...
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 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.
