STRUCTURAL-ANALYSIS OF A SUPERCONDUCTING CENTRAL SOLENOID FOR THE TOKAMAK PHYSICS EXPERIMENT

The Tokamak Physics Experiment (TPX) concept design uses superconducti ng coils to accomplish magnetic confinement. The central solenoid (CS) magnet is divided vertical Into 8 equal segments which are powered in dependently. The eddy current heating from the pulsed operation is too high for a case type construction; therefore, a ''no case'' design ha s been chosen. This ''no case'' design uses the conductor conduit as t he primary structure and the electrical insulation as a structural adh esive. This electrical insulation is the ''weak link'' in the coil win ding pack structure. A global finite element model with smeared windin g pack properties was used to study the CS magnet structural behavior. The structural analysis results and peak stresses will be presented.
