Abstract

The first superconducting planar undulator (SCU0) at the Advanced Photon Source (APS) has been built with the goal of providing the APS users with higher photon fluxes at higher photon energies. The undulator magnetic structure is wound with NbTi superconducting wire. The magnet is indirectly cooled by liquid helium circulating in a closed circuit. The cooling of the helium circuit, the current leads, and the thermal shields are provided by four cryocoolers. After a rigorous stand-alone cold test the undulator has been installed into the APS storage ring. The results of the SCU0 cold test are presented in this paper.
