Experiments with all-Kapton insulation and axial prestress in 1.8 m-long SSC R&D magnets

Several 1.8-m-long magnets have been built to evaluate possible variations in the design of the Superconducting Super Collider (SSC) dipoles. Except for length and the parameters being tested, these models have the features of 40-mm-aperture collider dipoles, which are based on a two-layer cosine theta coil. In these magnets, all-Kapton cable insulation and the effects of changes in the axial coil prestress have been tested. Construction details and test results for quenching, field harmonics, and coil loading are reported.<
