Design of a poly-Bitter magnet at the NHMFL

Abstract

The world's first 33 Tesla resistive magnet is being designed and built at the National High Magnetic Field Laboratory in Tallahassee, FL. Completion of the magnet is expected in the fourth quarter of 1995. It will produce a peak on-axis field greater than 33 Teslas in a 32 mm warm bore while consuming 20 megawatts of power. This magnet consists of two small concentric parallel coils (poly-Bitter) in series with two larger Bitter coils. Details of optimization calculations and the resulting magnet design and construction are presented.
