Description

European XFEL is planning the installation of superconducting undulators as afterburners downstream with respect to SASE2, one of the hard X-ray undulator lines, to provide even harder X-ray photon energies and a larger tuning range. The Superconducting undulator PRE-SerieS mOdule (S-PRESSO) consisting of two pair of coils, a phase shifter, and correction coils is in production by Bilfinger Nuclear & Energy Transition GmbH.

In order to perform quality assurance of the superconducting coils a vertical test stand SUNDAE 1 (Superconducting UNDulAtor Experiment) has been developed. SUNDAE1 allows to train the superconducting coils, as well as to measure the magnetic peak field profile by means of Hall probes. We report here on first results.
