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.

Public Data Set: Continuous, Edge Localized Ion Heating During Non-Solenoidal Plasma Startup and Sustainment in a Low Aspect Ratio TokamakThis public data set contains openly-documented, machine readable digital research data corresponding to figures published in M.G. Burke et. al., 'Continuous, Edge Localized Ion Heating During Non-Solenoidal Plasma Startup and Sustainment in a Low Aspect Ratio Tokamak,' Nucl. Fusion 57, 076010 (2017).
Facilitating the very short and intense pulses from an X-ray laser for the purpose of imaging small bioparticles carries the potential for structure determination at atomic resolution without the need for crystallization. In this study, we explore experimental strategies for this idea based on datamore »
Evolution patterns and parameter regimes in edge localized modes on the National Spherical Torus ExperimentWe implement unsupervised machine learning techniques to identify characteristic evolution patterns and associated parameter regimes in edge localized mode (ELM) events observed on the National Spherical Torus Experiment. Multi-channel, localized measurements spanning the pedestal region capture the complex evolution patterns of ELM events on Alfvenmore »
Integrated simulations of tokamak discharges typically rely on classical physics to model energetic particle (EP) dynamics. However, there are numerous cases in which energetic particles can suffer additional transport that is not classical in nature. Examples include transport by applied 3D magnetic perturbations and, moremore »
The Coso Magnetotelluric (MT) dataset of which the West Flank FORGE MT data is a subset, was collected by Schlumberger / WesternGeco and initially processed by the WesternGeco GeoSolutions Integrated EM Center of Excellence in Milan, Italy. The 2011 data was based on 99 soundingsmore »
