Common Coil Dipole for High Field Magnet Design and R&D

Abstract: The common coil geometry provides an alternate design to the conventional cosine theta dipoles. It allows a wider range of conductor and magnet technologies. It also facilitates a low-cost, rapid-turn-around design and R&D program. Recent studies carried out as a part of the US Magnet Development Program revealed that at high fields (20 T with 15% operating margin or more), the common coil design also uses significantly less conductor (particularly much less HTS), as compared to that in the other designs.
