Abstract (englisch):
Undulators are X-ray sources that are widely utilised
in advanced synchrotron radiation sources and free-electron laser
facilities. Due to sustainability and energy efficiency, the devel-
opment focuses on small-scale, high-field, and especially compact
undulators with short period lengths (≤ 10 mm) and narrow
magnetic gaps (≤ 4 mm). Therefore, high-temperature supercon-
ducting (HTS) tapes, which can provide a high critical current
density and high critical magnetic fields at higher temperatures,
are extensively used and investigated at the Karlsruhe Institute of
Technology. A new concept of superconducting undulators (SCUs)
was introduced and further developed by laser-scribing a meander
pattern into the superconducting layer to achieve a quasi-sinusoidal
current path through the HTS tape. Here we present the complete
and final design of such a compact SCU, in particular our latest
results regarding the design of the liner with its tapering in the
warm region, as well as the cryogenic cooling concept.
