Superconducting magnets are an invaluable tool for scientific discovery, energy research, and medical diagnosis. To date, virtually all superconducting have been made from two Nb-based low-temperature superconductors (Nb-Ti with a transition temperature Tc of 9.2 K Nb3Sn 18.3 K). The 8.33 T Nb-Ti accelerator dipole the large hadron collider (LHC) at CERN enabled discovery Higgs Boson ongoing search physics beyond standard model high physics. 12 class key to International Thermonuclear Experimental Reactor (ITER) Tokamak high-luminosity upgrade LHC that aims increase luminosity by factor 5–10. In this paper, we discuss opportunities high-temperature material Bi-2212 80–92 building more powerful circular colliders. development magnet could not succeed without parallel performance conductor. We will review triumphs developing round wires into grade conductor technologies enable them. Then, challenges associated constructing high-field using wires, especially those dipoles 15–20 significant value future colliders, potential technology paths forward, progress so far subscale based on racetrack coils canted-cosine-theta design uniquely addresses mechanical weaknesses cables. Additionally, roadmap being implemented US Magnet Development Program demonstrating is presented.
