Design and Manufacturing of an HTS Helical Undulator Demonstrator for Compact FELs / Richter, S C (CERN ; KIT, Karlsruhe) ; Ballarino, A (CERN) ; Bernhard, A (KIT, Karlsruhe) ; Müller, A S (KIT, Karlsruhe)
Among all superconducting undulator geometries, a helical undulator provides a very compact geometry and further is more effective in producing synchrotron radiation, providing circularly polarized photons, which are widely usable for synchrotron radiation users. These characteristics make it a very attractive option for realizing more compact free-electron lasers, requiring a combination of short-period and high-field undulators to produce coherent light up to X-rays.
