Test results of post-ASST design Fermilab built 1.5 meter, SSC collider model dipole magnets

摘要

A series of 1.5-m-long and 50-mm-aperture model Superconducting Super Collider (SSC) dipole magnets was built and tested at Fermilab. Later models were built to test several extensions to the Fermilab design and variations in the manufacturing parameters. Some of the variations tested included a conductor insulation scheme, alternate materials for coil end parts, and coil winding. The coils were instrumented with voltage traps for the pppes of quench localization and with strain gages to measure the stresses and deflections in the coil and magnet support structure. Data from the quench performance, coil stress, end force, and harmonics are presented and compared with design expectations and correlated with changes in the magnet design and assembly methods.
