Summary

A CEA-CNRS French collaboration is currently developing a new hybrid magnet. This magnet combines a resistive insert, composed of Bitter and polyhelix coils, and a large bore superconducting coil (subsequently named "outsert" due to its outermost location), to create an overall continuous magnetic field of 43 T in a 34 mm warm bore aperture. The superconducting coil, based on the novel development of a Nb-Ti/Cu Rutherford Cable On Conduit Conductor cooled down to 1.8 K by a bath of superfluid helium at atmospheric pressure, aims at producing a continuous magnetic field of 8.5 T in a 1.1 m cold bore diameter. The cryogenic requirements will be presented together with design principles and parameters.
