Training and Magnetic Field Measurements of the ANKA Superconducting Undulator

In this contribution we report the results of the training and of the local field measurements performed in a liquid helium bath of the ANKA superconducting undulator. The period length is 15 mm and the coils are 1.5 m long. The key specifications of the system are an undulator parameter K higher than 2 (for a magnetic gap of 5 mm) and a phase error smaller than 3.5 degrees. The superconducting undulator is planned to be installed in the ANKA storage ring by the beginning of 2011 to be the light source of the new beamline NANO for high resolution X-ray diffraction.
