Characteristics of the NASA Lewis Bumpy Torus Plasma Generated with Positive Applied Potentials

Abstract

Experimental observations have been made during steady-state operation of the NASA Lewis Bumpy Torus experiment at input powers up to 150 kW in deuterium and helium gas, and with positive potentials applied to the midplane electrodes. This steady-state ion heating method utilizes a modified Penning discharge operated in a bumpy torus confinement geometry… (More)
