These SCUs require new undulator magnets to achieve the required performance of the new machine. The magnets are fabricated from low carbon steel and wound with NbTi superconductor. To meet the needs of the users of the new machine these magnets will be manufactured in different lengths and magnetic periods to accommodate SCUs in both inline and canted configurations. Because the magnets for the SCUs cannot be shimmed like permanent magnet undulators, they need to have very tight tolerances for the poles and the winding grooves. This poses unique manufacturing and fabrication challenges. This paper will cover the design of the 1.9 m long magnets for the inline SCUs, their measurement data, lessons learned from manufacturing, and an overview of design changes that were made for the magnets to be used in the canted SCU configurations.
