HTS undulators: status of prototype coils for compact FELs — •Sebastian C. Richter1,2, Daniel Schoerling1, Axel Bernhard2, Kantaphon Damminsek2, Julian Gethmann2, and Anke-Susanne Müller2,3 — 1CERN - 1211 Geneva 23 - Switzerland — 2LAS, KIT, Karlsruhe, Germany — 3IBPT, KIT, Karlsruhe, Germany
Compact free electron lasers (FELs) require short-period high field undulators in combination with shorter accelerator structures to produce coherent light up-to X-rays. Applying high-temperature superconductor (HTS) in form of coated REBCO tape conductors allows reaching higher magnetic fields and larger operating margins as compared to low-temperature superconductors (LTS). This contribution discusses and summarizes the potential of HTS for the major superconducting undulator geometries (horizontal, vertical racetrack and helical) as well as the status of prototype coils for each type, to be wound with coated REBCO tape conductor.
