Abstract

A study was performed on the performance and stability of near-unity aspect ratio plasmas in the Pegasus Toroidal Experiment. By operation at low field with densities upto to the Greenwald limit, high toroidal beta β_t was obtained in ohmically-heated plasmas. The results showed that the values of β_t up to 20% and normalized beta up to 5 was obtained.
