Abstract

The Tokamak Physics Experiment (TPX) concept design uses superconducting coils to accomplish magnetic confinement. The central solenoid (CS) magnet is divided vertical 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 “no case” design has been chosen. This “no case” design uses the conductor conduit as the primary structure and the electrical installation as a structural adhesive. This electrical insulation is the “weak link” in the cell winding pack structure. 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
