TMX-axisymmetric magnet set design study

Studies are currently being made to design an axisymmetric modification to the TMX-Upgrade experiment. The existing TMX-Upgrade quadrupole plug and transition magnet sets are replaced by the circular coils of an axisymmetric plug. The existing TMX-Upgrade magnet set is shown. The circular coils are sectioned to show the quadrupole magnets and the flux bundle. The two end cells of this magnet set are MHD stable minimum-B plugs. From a mechanical design viewpoint, an axisymmetric design is attractively simple. One of the axisymmetric designs under consideration is the Modified Cusp. A magnet set for this designs is shown. The coils are sectioned to show their cross-section.
