The Future Circular electron-positron Collider, FCC- ee, is designed for unprecedented precision for particle physics experiments from the Z-pole up to above the top-pair-threshold, corresponding to a beam energy range from 45.6 to 182.5 GeV. Performing collisions at various particle-physics resonances requires precise knowledge of the centre-of-mass energy (ECM) and collision boosts at all four interaction points. [...]

A transverse gradient undulator (TGU) is a key component compensating for the relatively large energy spread of Laser Wakefield Accelerator (LWFA)-generated electron beams for realizing a compact Free Electron Laser (FEL). A superconducting TGU with 40 periods has been fabricated at the Karlsruhe Institute of Technology (KIT). [...]

Plasma accelerators present one of the most suitable candidates for the development of more compact particle
acceleration technologies, yet they still lag behind radiofrequency (RF)-based devices when it comes to beam quality,
control, stability and power efficiency. The Horizon 2020-funded project EuPRAXIA (“European Plasma Research
Accelerator with eXcellence In Applications”) aims to overcome the first three of these hurdles by developing a
conceptual design for a first international user facility based on plasma acceleration. [...]

The Horizon 2020 Project EuPRAXIA (European Plasma Research Accelerator with eXcellence In Applications) is producing a conceptual design report for a highly compact and cost-effective European facility with multi-GeV electron beams accelerated using plasmas. EuPRAXIA will be set up as a distributed Open Innovation platform with two construction sites, one with a focus on beam-driven plasma acceleration (PWFA) and another site with a focus on laser-driven plasma acceleration (LWFA).

Design and System Integration of the Superconducting Wiggler Magnets for the Compact Linear Collider Damping Rings
/ Schoerling, D (T.U. Bergakademie Freiberg ; CERN) ; Antoniou, F (CERN) ; Bernhard, A (CFN, Karlsruhe) ; Bragin, A (Novosibirsk, IYF) ; Karppinen, M (CERN) ; Maccaferri, R (CERN) ; Mezentsev, N (Novosibirsk, IYF) ; Papaphilippou, Y (CERN) ; Peiffer, P (CFN, Karlsruhe) ; Rossmanith, R (CFN, Karlsruhe) et al.
To achieve high luminosity at the collision point of the Compact Linear Collider (CLIC) the normalized horizontal and vertical emittances of the electron and positron beams must be reduced to 500 nm and 4 nm before the beams enter the 1.5TeV linear accelerators. An effective way to accomplish ultra-low emittances with only small effects on the electron polarization is using damping rings operating at 2.86 GeV equipped with superconducting wiggler magnets.

Field Optimization for short Period Undulators
/ Peiffer, P (KIT, Karlsruhe) ; Bernhard, A (KIT, Karlsruhe) ; Rossmanith, R (KIT, Karlsruhe) ; Schoerling, D (CERN)
Undulators dedicated to low energy electron beams, like Laser Wakefield Accelerators, require very short period lengths to achieve X-ray emission. However, at these short period length (LambdaU ~ 5 mm) it becomes difficult to reach magnetic field amplitudes that lead to a K parameter of >1, which is generally desired. [...]
