Synchrotron light sources utilize special magnets – wigglers and undulators, to create high intensity photon beams for a wide user community. Superconducting technology offers the possibility of creating undulators with better performance than conventional hybrid or pure permanent magnet technologies.

An extensive program is underway at the Advanced Photon Source (APS) with the aim of developing a technology capable of building superconducting planar undulators for APS users. During a two-year R&D phase of the project we have built and successfully tested a number of short magnet prototypes. This has led us to a conceptual design of the first full-scale undulator that is currently being built. The APS upgrade program considers manufacture of three more superconducting devices. The status of the project is presented.

The first APS devices are based on the NbTi superconductor. Better properties of the Nb3Sn superconductor make it attractive for building short-period superconducting undulators. Such devices are of interest not only to light sources but also to the FEL community. A possible APS-FNAL collaboration on developing Nb3Sn undulators is suggested.
