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. [...]

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. [...]

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. [...]

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.

Bending Radius Limits of Different Coated REBCO Conductor Tapes - An Experimental Investigation with Regard to HTS Undulators
/ Richter, Sebastian C (CERN ; KIT, Karlsruhe, Dept. Phys.) ; Bernhard, Axel (KIT, Karlsruhe, Dept. Phys.) ; Drechsler, Antje (KIT, Karlsruhe, Dept. 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. [...]

Design of the First HTS Single-Coil Demonstrator of GaToroid Toroidal Gantry for Hadron Therapy
/ Felcini, Enrico (CERN) ; Harray, Jerome (CERN) ; Lehtinen, Tuukka (CERN) ; Perini, Diego (CERN) ; Perez, Juan C (CERN) ; de Rijk, Gijs (CERN) ; Dutoit, Bertrand (Ecole Polytechnique, Lausanne) ; Bottura, Luca (CERN)
The design and construction of compact and lightweight gantries for hadron therapy are essential steps toward wider accessibility to this cancer treatment. The use of a high-field steady-state toroidal gantry, i.e., GaToroid, represents an attractive alternative to the state-of-the-art with the potential of significantly reducing size and weight of present installations.

The EuCARD2 Future Magnets Program for Particle Accelerator High-Field Dipoles: Review of Results and Next Steps
/ Rossi, Lucio (CERN) ; Badel, Arnaud (IUT, Grenoble) ; Bajas, Hugues (CERN) ; Bajko, Marta (CERN) ; Ballarino, Amalia (CERN) ; Barth, Christian (Geneva U.) ; Betz, Ulrich (SIS GmbH) ; Bottura, Luca (CERN) ; Broggi, Francesco (LASA, Segrate) ; Chiuchiolo, Antonella (CERN) et al.
The EuCARD2 collaboration aims at the development of a 10 kA-class superconducting, high current density cable suitable for accelerator magnets, to be tested in small coils and magnets capable to deliver 3-5 T when energized in stand-alone mode, and 15-18 T when inserted in a 12-13 T background magnet. REBCO tape, assembled in a Roebel cable, was selected as conductor. [...]

Test Results of the CLIC Damping Wiggler Prototype

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. [...]
