Critical elements of FRIB are the dipole magnets which select the desired isotopes. Since conventional NiTi and Nb3Sn superconductors must operate at ~4.5 K, the removal of the high heat load generated in these magnets with these superconductors would be difficult. The coils for these magnets must accommodate the large curvature from the 30° bend that the magnets subtend. High temperature superconductors (HTS) have been shown to be radiation resistant and can operate in the 40 K temperature range where heat removal is an order of magnitude more efficient than at 4.5 K. This paper will describe the magnetic and preliminary engineering design of these magnets.

Magnets in the fragment separator region of the Facility for Rare Isotope Beams (FRIB) would be subjected to extremely high radiation and heat loads. Critical elements of FRIB are the dipole magnets which select the desired isotopes. Since conventional NiTi and Nb3Sn superconductors must operate at ~4.5 K, the removal of the high heat load generated in these magnets with these superconductors would be difficult. The coils for these magnets must accommodate the large curvature from the 30° bend that the magnets subtend. High temperature superconductors (HTS) have been shown to be radiation resistant and can operate in the 40 K temperature range where heat removal is an order of magnitude more efficient than at 4.5 K. This paper will describe the magnetic and preliminary engineering design of these magnets.
