TI - HTS/lTS Hybrid High Field Superconducting Magnet Designs for the Proposed 100 TeV Proton Colliders J2 - Proc. of IPAC2015, Richmond, VA, USA, May 3-8, 2015 C1 - Richmond, VA, USA T2 - International Particle Accelerator Conference T3 - 6 LA - english AB - Proposed proton-proton colliders with a center-of-mass energy up to 100 TeV in a tunnel of desired size require the dipole magnets to be of very high field–20 teslas in some proposals. This field is beyond the limit of present conventional Low Temperature Superconductors (LTS) and requires using High Temperature Superconductors (HTS). The preliminary magnetic design presented in this paper is an HTS/LTS hybrid design with high strength HTS tape used in higher field regions and less expensive LTS in lower field regions, with a goal of optimizing the performance while reducing the cost. A major concern in the magnets built with the HTS tape is the large field errors associated with the conductor magnetization. The strategy presented here aims to reduce those errors considerably. This paper also presents a proof-of-principle design and program to experimentally evaluate that concept.
