Users at the Advanced Photon Source (APS) requested a special purpose undulator that required 456 electromagnetic coils. This paper discusses the design and fabrication techniques used at the APS to build these room-temperature coils. The coils are made from insulated square copper conductor and are vacuum impregnated with epoxy.
