Higher critical temperatures on the order of 20 K allow the magnets to operate under signifi cant thermal loads during the fusion process. As a case study, we look at the proposed SPARC toroidal field (TF) magnet design. We investigate the heat transfer inside the cooling channels and uid dynamics inside the cooling channels. System-level issues are also investigated, including impact of an insulated versus non-insulated design on cooling performance and cryodistribution architectures to provide coolant during fusion.
