Superconducting insertion devices (IDs) are very attractive for synchrotron light sources since they allow increasing the flux and/or the photon energy with respect to permanent magnet IDs. Babcock Noell GmbH (BNG) is completing the fabrication of a 1.5 m long unit for ANKA at the Research Center in Karlsruhe (FZK). The period length of the device is 15 mm for a total of 100.5 full periods plus an additional matching period at each end. The key specifications of the system are: a K-value higher than 2, the capability of withstanding a 4 W beam heat load and a phase error smaller than 3.5 degrees. The magnet is in the final stages of the winding process and will be soon tested at CERN in liquid helium in vertical configuration. This paper describes the main features of the system, the results of the prototyping phase and details of manufacturing process.
