First X-rays from a novel full-scale superconducting undulator at ANKA: Higher magnetic peak field than cryogenic permanent magnet devices

摘要

The ANKA Synchrotron Radiation Facility at KIT and Babcock Noell GmbH (BNG) are pursuing a Research & Development program on superconducting undulators (SCUs). The collaboration focuses on conductioncooled SCUs with NbTi superconductor coils and a variable vacuum gap. Since SCUs can reach higher magnetic peak fields than permanent magnet in-vacuum insertion devices, including cryogenic ones (for the same gap and period length), they have the potential to increase the spectral range, brilliance and flux of existing state-of-the-art devices.
