18T Hybrid Dipole

Pushing future accelerators to higher collision energies will require an increase in either the bending radius of the collider or the dipole field strength. Presently, the LHC uses NbTi magnets capable of generating field strengths up to ~8.3 T. Nb3Sn magnets which have reached up to 16 T, but to reach 20 T and above we must incorporate high-temperature superconductors (HTS) – REBCO or Bi-2212. While that bridge of cost – HTS are much more expensive – is being crossed, a hybrid dipoles have recently gained much interest in the field of magnet development.

REBCO Insert Winding

Nb3Sn Outsert Winding

  • In the conformal winding method presented, the tape windings are angled turn-to-turn
  • thereby maximizing their current carrying capacity and reducing the required amount of REBCO.

    REBCO tapes conformally aligned with the direction of the field
  • Composed of Nb3Sn SuperCIC, which can be fabricated separately from the insert and heat treated
  • Capable of much higher fields than NbTi

Nb3Sn Outsert Winding

  • Due to our conformal winding method, the current density in the tapes can be maximized
  • the maximized current density reduces the cost of the REBCO far below the perceived cost
