The Pegasus Toroidal Experiment is a plasma confinement experiment relevant to fusion power production, run by the Department of Engineering Physics of the University of Wisconsin–Madison. It is a spherical tokamak, a very low-aspect-ratio version of the tokamak configuration, i.e. the minor radius of the torus is comparable to the major radius.
Local Helicity Injection
Pegasus is used to study start up of spherical tokamaks using local helicity injection.[https://conferences.iaea.org/indico/event/151/contributions/5724/attachments/6926/9614/Bongard_EX_P6-34.pdf Advancing Local Helicity Injection for Non-Solenoidal Tokamak Startup Bongard 2018]{{Cite web |url=https://pegasus.ep.wisc.edu/Technical_Reports/pdf/Abstracts/JAG_SOFE19_Abstract.pdf |title=URANIA: A Dedicated Spherical Tokamak Experiment for Developing Non-Solenoidal Plasma Startup Techniques |access-date=2019-05-04 |archive-date=2019-05-04 |archive-url=https://web.archive.org/web/20190504101614/https://pegasus.ep.wisc.edu/Technical_Reports/pdf/Abstracts/JAG_SOFE19_Abstract.pdf |url-status=dead }}
URANIA
Pegasus is being upgraded in 2019 (e.g. by removal of the central solenoid) to build the Unified Reduced Non-Inductive Assessment (URANIA) experiment. This will study plasma startup using transient coaxial helicity injection (CHI).
The max toroidal field is being increased from 0.15 T to 0.6 T, and the pulse duration from 25 to 100 ms.{{Cite web |url=https://pegasus.ep.wisc.edu/Technical_Reports/pdf/APSDPP/JAR_APS18.pdf |title=Research Directions on the Pegasus Toroidal Experiment Reusch 2018 |access-date=2019-05-04 |archive-date=2019-05-04 |archive-url=https://web.archive.org/web/20190504104100/https://pegasus.ep.wisc.edu/Technical_Reports/pdf/APSDPP/JAR_APS18.pdf |url-status=dead }}
