THE US 100-T MAGNET PROJECT

A design is presented of a 100 T research magnet to generate high held pulses having lengths of more than 20 ms at field levels of above 80 T. The magnet is designed to be nondestructive, have a bore of 24 mm a nd a repetition rate of less than 1 h. It consists of a 50 T outer mag net, constructed of five concentric, mechanically independent coils, p owered from a motor-generator, and a self-supporting 50 T insert magne t, which is energized from a capacitor bank. The design is based on co mmercially available materials. The magnet has an overall diameter and total length of approximately 1 m.
