Notes:
The design of the insertion devices built and tested by STI Optronics for the Advanced Photon Source (APS) have used initial Halbach scoping followed by 2D and 3D finite element analysis (FEA). We review our design methods, which ensure the fabricated devices achieve the requested on-axis field strength, minimize pole saturation and demagnetizing fields, and reduce harmonic content, transverse roll-off, and flux leakages to desired levels. Recent enhancements include additional assessment of the effects of excessively strong magnets, magnet inhomogeneity, transverse pole saturations, part placement sensitivity, and refinements in the material databases used by the FEA. © 1996 American Institute of Physics.
