Structural Analyses of the Cold Mass for High Field Dusty Plasma Experiment

A magnet to study the properties of dusty plasmas in the presence of a magnetic field has been proposed. This magnet has four operating modes to vary the experimental test region and target magnetic field values. The design of the cold mass for the high field magnetized dusty plasma experiment is presented and analyzed. The cold mass includes four coils, ground insulation covering the winding packs, and coil cases used to safely support the coils. Dimensions of the four coils are specified by the magnetic design, and the equipment used to view the dusty plasma apply spatial constraints to the cold mass design. The design also considers the manufacturing process for the cold mass and the stresses resulting from electromagnetic loads coupled with thermal loads. Only one operating mode is considered in this analysis as the others produce significantly lower electromagnetic forces. Resulting stresses compare favorably to failure criteria at critical locations.
