Abstract
It has been discovered that plasma containment by a chamber having multi-pole magnetic cusp reflecting walls in combination with electronic injection for electrostatic containment provides the means for generating magnetic field free quiescent plasmas for practical application in ion-pumps, electronic switches, and the like. 1250 "Alnico V" magnets 1/2".times.1/2".times.11/2" provide containment in one embodiment. Electromagnets embodying toroidal funneling extend the principle to fusion apparatus.
