The goal of the common coil magnet R&D program at Brookhaven National Laboratory (BNL) is to develop a high field (12.5 T) magnet design using "React and Wind" technology. The common coil design is a 2-in-1 block design based on flat racetrack coils with large bend radii in the ends. The design offers a "conductor friendly" geometry that is suitable for brittle materials and for containing large Lorentz forces. The overall program is geared to carry out innovative magnet R&D in a time and cost effective
manner. This should help develop alternate designs and technologies that can be eventually used by industry to carry out a large scale magnet production at a significantly lower cost. In Phase I of this program, a proof of principle 6 T, NbTi dipole was built and commissioned which now serves as a background field test facility for HTS coils. Phase II of this program will utilize more engineering resources. In addition to HTS tapes, Nb₃Sn and HTS cables will also be used.
