45 T, Steady State

We discuss methods and results of calculations for hybrid magnet systems for extremely intense continuous magnetic fields. We focus on a system consisting of a 20 MW radially-cooled insert magnet of 33 mm bore and 406 mm outer diameter, operating within the bore of a 15 T superconducting magnet. We predict such a system to be capable of 45.5 T, given typical cooling-system parameters and the structural efficiency which we expect of our “monohelix” form of construction.
