THEORETICAL ASPECTS OF ENERGY CONFINEMENT IN SPHEROMAKS

Despite the poor global energy confinement observed in spheromak exper iments to dare, the long-term prospects may be favorable as spheromaks are scaled to larger size and higher temperatures. The present perfor mance is traced to excessive magnetic energy loss at the edge compared to tokamaks and hear transport due to magnetic fluctuations, both of which should scale away as the temperature increases.
