Abstract

A new water-cooled poly Bitter magnet for a hybrid magnet was designed under the fully utilization of the electric power source of 8 MW and the cooling system installed in the High Field Laboratory for Superconducting Materials, Tohoku University. The magnet consists of four axial water-cooled Bitter coils, which are electrically connected in series and all of cooling water flows from the bottom to upper side of coils. The designed poly Bitter magnet will produce 22.8 T by 7.5 MW in the room temperature bore of 16 mm and 34.3 T as a hybrid magnet with a backup field of 11.5 T. A magnetic force field, B(∂B/∂z), reaches to approximately -11, 100 T2/m at the central field of 34.3 T, which is very large enough to levitate semiconductors such as silicon or germanium.
