Title: An Overview of Magnet Science and Technology at the MagLab

Abstract: This Colloquium will present an overview of the status of activities in Magnet Science and Technology at the MagLab.

  • The 32 T superconducting magnet is the first magnet worldwide using High Temperature Superconductors (HTS) at >24 T intended to be used for physics research to attain 32 T. It is presently assembled in the millikelvin facility where completion of the instrumentation and controls system is underway.
  • The MagLab has now embarked on the development a 40 T HTS magnet also for condensed matter physics, building on the technology developed for the 32 T magnet.
  • There are a number of other HTS magnet projects that are gaining traction including magnets for the University of California at Santa Barbara’s Free Electron Laser Facility, The Cornell High Energy Synchrotron Source, and the Helmholtz Zentrum Berlin.
  • Winding of coils for pulsed magnets is again happening at the FSU branch of the MagLab! We have applied the expertise gained winding large superconducting coils for the 900 MHz NMR magnet and the Nb3Sn Cable-In-Conduit coils to start winding the coils for the 60 T Long-Pulse and 100 T magnet at our Los Alamos branch. We have implemented a number of improvements to the process, particularly providing better inspection of the wire. These, coupled with upgrades to wire-drawing equipment at the MagLab are showing potential for improvements in performance of these large pulsed magnets.
  • A 41.5 T resistive magnet, another first worldwide, is expected to start serving users in September.
