Abstract

Worldwide several superconducting electron cyclotron resonance (ECR) ion sources have been developed and in operation for heavy ion accelerators using Nb-Ti magnets. To explore the use of high-field Nb

$_{3}$

Sn to break the field limit of Nb-Ti for ECR magnets, state-of-the-art Nb

$_{3}$

Sn coil fabrication techniques and tooling design must be used to address the challenging characteristics of Nb

$_{3}$

Sn conductors. Earlier we reported the overall magnet design, conductor selection, and conductor characterization for building a 28 GHz superconducting ECR ion source using Nb

$_{3}$

Sn sextupole coils for Facility for Rare Isotope Beams (FRIB). This paper describes the progress towards fabricating prototype Nb

$_{3}$

Sn sextupole coil. In particular, we present tooling design, Nb

$_{3}$

Sn sextupole coil fabrication, and a mirror magnet for performance verification.
