Description

Several superconducting electron cyclotron resonance (ECR) ion sources for heavy ion accelerators are in operation around the world. These rely primarily on magnets wound using Nb-Ti conductors. Development toward the use of Nb$_{3}$Sn conductor as an alternative conductor is advancing, with higher magnetic field limits resulting in higher intensity high charge beams being a primary motivation. In this context, Lawrence Berkeley National Laboratory (LBNL) is building a sextupole-in-solenoid magnet for a previously reported proof-of-concept 28 GHz superconducting ECR ion source for the Facility for Rare Isotope Beams (FRIB). A prototype Nb$_{3}$Sn sextupole coil identical to the planned series of coils has been fabricated. It is tested using a mirror magnet structure. Earlier on we reported the tooling and process we developed to manage challenges arising from using Nb$_{3}$Sn for ECR ion source magnet. Here we report details of the prototype coil fabrication, mirror structure, and test results.
