SUMMARY:New Possibilities for Ultra-high Field Superconducting Magnets
 \, Physics Department Colloquium\, David Larbalestier\, National High 
 Magnetic Field Laboratory
DESCRIPTION:Two recent NRC reports have described the scientific and t
 echnology rationales for many new types of ultra-high field magnet: ms
 ec 150 T pulsed\, pulsed 40 T for neutron or x-ray scattering\, region
 al 32 T superconducting (SC)\, 40 T SC\, 28 – 37 T high-resolution N
 MR\, 25 – 40 T SC for x-rays and neutrons\, 60 T DC\, 20 T for human
  MRI\, as well as magnets for fusion\, particle-accelerators\, radioth
 erapy\, axion and other particle detectors. The materials and magnet t
 echnology have now made sufficient progress that a few of these magnet
 s are now feasible.  I will describe this progress and the various plu
 ses and minuses of the three present high-temperature superconductor t
 ypes and suggest some timelines under which high field coils beyond th
 e capabilities of present-day Nb-Ti and Nb3Sn magnets might start to m
 ake it into commercial fabrication. We have shown that High Temperatur
 e Cuprate Superconductors can generate fields >40 T\, almost twice the
  Nb-based superconductor limit and in striking distance of the world r
 ecord 45 T DC field which requires 28 MW of DC power and a large Nb3Sn
  superconducting outsert magnet.
