React and Wind ${\rm Nb}_{3}{\rm Sn}$ Common Coil Dipole

This paper presents a summary of the design, construction and test results of a common coil dipole DCC017 made using ldquoreact & windrdquo Nb
₃
Sn technology. It reached the computed short sample field of 10.2 T at 10.8 kA after a number of quenches. In order to build high field magnets with brittle pre-reacted superconductors one must develop magnet designs, tooling and construction techniques that keep conductor degradation due to bending and handling to a tolerable level. The successful construction and test of this magnet demonstrates that it is possible to design and build magnets in the 10 (plus) T range using ldquoreact & windrdquo technology. The magnet is based on a 2-layer common coil design with a clear horizontal space of 31 mm. A unique feature of the design is a tall 338 mm clear vertical open space that can facilitate possible flat racetrack coil testing in a high background field without dis-assembling the magnet.
