First 100 T non-destructive magnet

The first 100 T non-destructive (100 T ND) magnet and power supplies as cur rently designed are described. This magnet will be installed as part of the user facility research equipment at the National High Magnetic Field Labor atory (NHMFL) Pulsed Field Facility at Los Alamos National Laboratory. The 100 T ND magnet will provide a 100 T pulsed field of 5 ms duration (above 9 0% of full field) in a 15 mm diameter bore once per hour. Magnet operation will be nondestructive. The magnet will consist of a controlled power outer coil set which produces a 47 T platform field in a 225 mm diameter bore. L ocated within the outer coil set will be a 220 mm outer diameter capacitor powered insert coil. Using inertial energy storage a synchronous motor/gene rator will provide ac power to a set of seven ac-dc converters rated at 64 MW/80 MVA each. These converters will energize three independent coil circu its to create 170 MJ of field energy in the outer coil set at the platform field of 47 T. The insert will then be energized to produce the balance of the 100 T peak field using a 2.3 MJ, 18 kV (charged to 15 kV), 14.4 mF capa citor bank controlled with solid-state switches. The magnet will be the fir st of its kind and the first non-destructive, reusable 100 T pulsed magnet. The operation of the magnet will be described along with special features of its design and construction.
