Design of the Outsert Coil of the 45 T Hybrid Magnet at the Nijmegen High Field Magnet Laboratory

The Nijmegen High Field Magnet Laboratory (Nijmegen HFML) is developing a 45 T hybrid magnet consisting of a 12 T CICC
${\rm Nb}_{3}{\rm Sn}$
superconducting outsert magnet and a 33 T Florida-Bitter resistive insert magnet. After a thorough review last year of the conceptual design of the superconducting outsert magnet in particular, the conductor and coil design for the outsert magnet have been adapted to create a larger performance margin so as to meet more adequately the possible uncertainties especially in CICC performance.
