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.
