Abstract :
The highest non-destructive fields are provided by pulsed field magnets. Monolithic coils are limited to 70-75 Tesla by mechanical and thermal constraints. These limitations can be circumvented through the use of multi-coil assemblies. At HFML, pulsed field magnets can be energized using either a 2 MJ, 16 kV capacitor bank or a state-of-the-art 20 MW DC power supply in pulsed mode; each of these sources is capable of delivering up to 20 kA. This would allow multi-coil operation at fields to above 80 T
