ON ELECTRICAL CONDUCTION IN A NON-UNIFORM HELIUM PLASMA.
Abstract
The plasma properties in the region close to a cylindrical cold anode surrounding a helium arc plasma were studied. The temperature profile of the heavy constituents (atoms, ions), is obtained from an Elenbaas-Heller equation. The electric field, the current density, the (elevated) electron temperatures and the electron density were calculated as functions of the distance from and the potential of the anode. A onedimensional model was used and a locally Maxwellian (about a drift velocity) electron distribution was assumed with the level of ionization determined by the Saha expression evaluated at the electron temperature.
