Abstract
Tokamak and Ohmically heated stellarator plasmas have been compared in the CLEO apparatus, using gas current in the range 10-25 kA at a toroidal field of 12.7 kG. It is found that the vacuum poloidal field due to the helical winding has a considerable influence on the containment properties. In particular, for the same current the electron energy per unit length is a factor of 2 greater in the stellarator than in the tokamak.Keywords
