Design, construction and test of a full scale SSC dipole magnet cryostat thermal model

As a part of the SSC main ring superconducting magnet development program, a full length dipole magnet thermal model has been constructed and its thermal performance measured. Presented are the details of the cryostat design and the thermal model construction experience and its evaluation. The methods for and the preliminary results of the thermal performance measurements are presented and compared with the predicted performance.
