Abstract (englisch):

The application of high-temperature superconductor
(HTS) in form of coated REBCO tape conductors to undulators and
wigglers allows reaching higher magnetic fields and larger operating
margins. Simulations have shown the capability to provide magnetic
fields greater than 2 T for undulator periods of 13 mm. Undulator
prototype coils are being designed and their performance will be
evaluated to make a final design choice for a six period short model.
This paper discusses and summarizes the potential of HTS for the
major superconducting undulator geometries (helical, horizontal
and vertical racetracks). Further, studies of prototype coils for an
undulator period of 13 mm, to be built from 4 mm wide REBCO
tape, are presented including first results from winding tests.
