For a muon collider with copious decay particles in the plane of the storage ring, open-midplane dipoles (OMD) may be preferable to tungsten-shielded cosine-theta dipoles of large aperture. The OMD should have its midplane completely free of material, so as to dodge the radiation from decaying muons. Analysis funded by a Phase I SBIR suggests that a field of 10^-20 T should be feasible, with homogeneity of 1x10^-4 and energy deposition low enough for conduction cooling to 4.2 K helium. If funded, a Phase II SBIR would refine the analysis and build and test a proof-of-principle magnet.

High Temperature Superconductors (HTS) are now becoming a crucial part of future medium and high field magnet applications in several areas including accelerators, energy storage, medical and user facilities. A second generation HTS quadrupole is being constructed for the Facilities for Rare Isotope Beams (FRIB). The muon collider requires high field solenoids in the range of 40-50 T - an R&D that is partly supported by SBIRs and partly programs at various laboratories. Superconducting Magnetic Energy Storage (SMES) R&D, recently funded by ARPA-E, requires large aperture HTS solenoid in the range of 25-30 T. A user facility at National High Magnetic Field Laboratory (NHMFL) has been funded to develop a 32 T solenoid. All of these programs require HTS in a quantity never obtained before for magnet applications and would play a key role in developing HTS for magnet applications. High field magnets pose special challenges in terms of quench protection, large stored energy and large stresses, etc. This presentation will review various ongoing activities, and examine the future prospects of HTS magnets in a number of applications, with a particular emphasis on high field applications.
