DIFFUSION OF PLASMAS ACROSS A MAGNETIC FIELD,

Abstract

Experimental investigation of transport processes in cesium arc plasmas shows classical ambipolar diffusion across low magnetic fields, convective transport associated with the helical instability at intermediate fields, and a return, apparently to diffusive transport and relatively good confinement at magnetic fields ten to twenty times the critical field for the onset of the instability. Improved confinement is also achieved by using a hysteresis in the parameter space of the plasma operation, a procedure which may have wide applicability. (Author)
