Block-Coil High-Field Dipoles Using Superconducting Cable-in-Conduit

Dipoles with 15-20 T operating field are required for some designs of future hadron colliders. Such dipoles require the use of high-field superconductors Nb 3 Sn, Bi-2212, and REBCO. Designs are presented for hybrid block-coil dipoles using superconducting cable-in-conduit (CICC). CICC conveys sever...

Description
Summary:Dipoles with 15-20 T operating field are required for some designs of future hadron colliders. Such dipoles require the use of high-field superconductors Nb 3 Sn, Bi-2212, and REBCO. Designs are presented for hybrid block-coil dipoles using superconducting cable-in-conduit (CICC). CICC conveys several benefits that optimize cost and performance at high field: cable-level stress management; compact, robust flared ends; and in-cable cryogen flow. CICC windings uniquely make possible a hybrid coil configuration in which subwindings of Bi-2212, Nb 3 Sn, and NbTi can be separately wound and heat treated, and then assembled and preloaded in a compact assembly.
