Abstract

The main goal of the model coil is to demonstrate the feasibility of `Insulation-Wind-React´ manufacturing process and to confirm the feasibility of the superconducting outsert design. The model coil was wound with Cable-in-Conduit Conductor (CICC) using restacked-rod process (RRP) Nb³Sn strand, and cooled with forced-flow supercritical helium with inlet temperature of 4.5 K. The test of the model coil in the 7.5 T background field has been completed, and the test program included cool-down, full DC characterization before and after cyclic loading, AC losses, and so on. The test results have confirmed the characterization of the Nb₃Sn conductor and the mechanical performance of the model coil, and validated the 40 T hybrid magnet superconducting outsert design.
