A helical superconducting undulator (HSCU) has been installed and is presently operational at the Advanced Photon Source (APS) at Argonne National Laboratory (ANL). We describe the final assembly and cryogenic test program which led to successful operation, representing the culmination of a two-year development effort. Details of the cryostat and cryogenic system design are presented along with as-installed performance data and a comparison with design expectations.

A helical superconducting undulator (HSCU) was developed and installed at the Advanced Photon Source (APS). Implementation of a unique design of the helical coil former allowed for a compact turn around scheme of the conductor at the ends of the device during winding. Inherent to the coil winding design was the gradual reduction of the magnitude of the magnetic field at the ends of the device. The coil former design along with the magnetic measurement results will be described.

WEXGBF2	Development and Operational Experience of APS Superconducting Undulators
	E. Gluskin ANL, Argonne, Illinois, USA
	Addressing a demand by Advanced Photon Source (APS) users for high-intensity circular polarized photon beams, development has begun at APS on circular polarising undulators. The first such device is currently being built for the APS storage ring. It is based on a superconducting magnet with a conventional double-helical coil structure. This helical superconducting undulator will be completed in 2017. In addition, the concept of a novel SuperConducting Arbitrarily Polarizing Emitter (SCAPE) has been suggested and is now under development. It consists of two pairs, both vertical and horizontal, of superconducting magnets assembled around a beam vacuum chamber. Such a device is capable of generating either planar or circular polarized photons, depending on which pair of magnets is energized. The SCAPE undulators could be attractive for the APS Upgrade and other fourth-generation storage rings with a multi-bend achromat lattice, as well as for FELs where utilization of round beam vacuum chambers becomes possible. This invited talk presents the status of work on the helical SCU, as well as a conceptual design of the SCAPE.
