The Pegasus Toroidal Experiment [1] is a mid-sized, extremely low aspect ratio spherical torus. Access to near-unity aspect ratio is achieved through use of a novel highstress reinforced solenoid magnet assembly. It has the dual roles of exploring the limits of spherical torus plasma behavior as the aspect ratio, A, approaches 1 and examining alternate confinement concepts in the tokamak-spheromak overlap regime.
