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 ad the electrical insulation as a structural adhesive. This electrical insulation is the weak link in the coil winding pack structure. A global finite element model with smeared winding pack properties was sued to study the CS magnet structural behavior. The structural analysis results and peak stresses will be presented.
