Title: Pegasus Toroidal Experiment

The Pegasus Toroidal Experiment is an ultra-low aspect ratio spherical tokamak at the University of Wisconsin-Madison. Its research program is part of a worldwide effort to enhance the understanding of high-temperature plasma behavior and magnetic confinement, with focus on addressing areas of critical concern to understanding the spherical tokamak for fusion science advancement. These include: plasma initiation without the use of a central solenoid through local helicity injection; core and edge magnetohydrodyamic stability studies; and validation studies of predictive plasma models.
