Structural analysis of a superconducting central solenoid for the Tokamak Physics Experiment

OSTI ID:10190564
The Tokamak Physics Experiment (TPX) concept design uses superconducting coils to accomplish magnetic confinement. The central solenoid (CS) magnet is divided vertically into 8 equal segments which are powered independently. The eddy current heating from the pulsed operation is too high for a case type construction; therefore, a {open_quotes}no case{close_quotes} design has been chosen. This {open_quotes}no case{close_quotes} design uses the conductor conduit as the primary structure and the electrical insulation as a structural adhesive. This electrical insulation is the {open_quotes}weak link{close_quotes} in the coil winding pack structure and needs to be modeled in detail. A global finite element model with smeared winding pack properties was used to study the CS magnet structural behavior. The structural analysis results and peak stresses will be presented.
