Description
Abstract
The NHMFL has developed and built a 32 T superconducting user magnet for low-temperature, high-magnetic-field experiments. Combining LTS and HTS magnet technology, this magnet is likely to be the first superconducting user magnet operating well beyond the limits of Nb-based LTS technology. Significant technology development specific to HTS coils, and HTS-LTS interaction during quench, was required. Key topics in this presentation are conductor specifications, temperature margins, liquid helium levitation and quench protection using quench heaters. Lessons learned from prototype coils, conductor characterization, construction, quench calculations and initial testing of the 32 T magnet at 77 K are presented.
