High-Temperature Superconducting Undulator Prototype Coils for Compact Free-Electron Lasers
/ Richter, S C (CERN ; KIT, Karlsruhe) ; Ballarino, A (CERN) ; Bernhard, A (KIT, Karlsruhe) ; Grau, A W (KIT, Karlsruhe) ; de Jauregui, D Saez (KIT, Karlsruhe) ; Müller, A S (KIT, Karlsruhe)
Short-period and high-field undulators are crucial for the production of coherent light up to X-rays in compact free-electron lasers (FELs). Besides, future colliders like CLIC or FCC-ee demand high-field damping wigglers to reach a low beam emittance. [...]

Progress on HTS Undulator Prototype Coils for Compact FEL Designs
/ Richter, S C (CERN ; KIT, Karlsruhe) ; Ballarino, A (CERN) ; Schoerling, D (CERN) ; Nes, T H (CERN) ; Bernhard, A (KIT, Karlsruhe, IKP) ; Müller, A S (KIT, Karlsruhe)
Compact free-electron lasers require short accelerator structures followed by high peak field and short-period undulators to produce coherent radiation up to hard X-rays. Likewise, future lepton colliders, like CLIC or FCC-ee, require high-field damping wigglers for the creation of low emittance beams. [...]

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.

Status and Powering Test Results of HTS Undulator Coils at 77 K for Compact FEL Designs
/ Richter, Sebastian (CERN ; KIT, Karlsruhe, EKP) ; Ballarino, Amalia (CERN) ; Bernhard, Axel (KIT, Karlsruhe, EKP) ; Müller, Anke-Susanne (KIT, Karlsruhe, EKP) ; Nes, Thomas (CERN) ; Schoerling, Daniel (CERN)
The production of low emittance positron beams for future linear and circular lepton colliders, like CLIC or FCC-ee, requires high-field damping wigglers. Just as compact free-electron lasers (FELs) require high-field but as well short-period undulators to emit high energetic, coherent photons. [...]

Bending Radius Limits of Different Coated REBCO Conductor Tapes - An Experimental Investigation with Regard to HTS Undulators

Phys.) ; Müller, Anke-Susanne (KIT, Karlsruhe, Dept. Phys.) ; Ringsdorf, Bernd (KIT, Karlsruhe, Dept. Phys.) ; Schlachter, Sonja I (KIT, Karlsruhe, Dept. Phys.) ; Schoerling, Daniel (CERN)
Compact FELs require short-period, high-field undulators in combination with compact accelerator structures to produce coherent light up to X-rays. Likewise, for the production of low emittance positron beams for future lepton colliders, like CLIC or FCC-ee, high-field damping wigglers are required. [...]

The Compact Linear Collider (CLIC) will require ultralow emittance electron and positron beams. Such emittance will be achieved by radiative damping in the CLIC damping rings that will be realized by a use of high-field short-period superconducting damping wigglers. [...]
