Conceptual design of 20 T dipoles for high-energy LHC

  title={Conceptual design of 20 T dipoles for high-energy LHC},
  author={Lucio Rossi and Ezio Todesco},
Availability of 20 T operational field dipole magnets would open the way for a 16.5 TeV beam energy accelerator in the LHC tunnel. Here we discuss the main issues related to the magnet design of this extremely challenging dipole: main constraints, superconductor choice, coil lay-out, iron, forces and stresses, and field quality. A tentative cost estimate is also given. The present technology, based on Nb-Ti and now near to be extended to Nb3Sn superconductor, would allow reaching 15 T…
