To demonstrate a Mixed Axial and Radial field System (MARS) as the best magnet scheme for future ECRISs, MARS-D, demonstrative ECRIS using NbTi MARS is progressing at Lawrence Berkeley National Laboratory. An optimized design can use either or Nb3Sn coils with reduced engineering complexities to construct needed high-field magnets. The could enhance MARS-D next generation by producing minimum-B maxima of 5.6 T axially 3.2 radially operating frequencies up 45 GHz. In-progress test winding has achieved milestone demonstrating fabrication feasibility closed-loop coil.
