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.

Curved-Canted-Cosine-Theta (CCCT) Dipole Prototype Development at CERN
/ Haziot, Ariel (CERN) ; Kirby, Glyn (CERN) ; Dallocchio, Alessandro (CERN) ; Devred, Arnaud (CERN) ; Foussat, Arnaud (CERN) ; Gentini, Luca (CERN) ; Mangiarotti, Franco J (CERN) ; Pentella, Mariano (CERN) ; Petrone, Carlo (CERN) ; Pincot, Francois-Olivier (CERN) et al.
Due to its flexibility in generating advanced field harmonic corrections and potential for low cost compared to traditional designs, the Canted Cosine Theta (CCT) configuration is particularly interesting for compact particle accelerators and gantries for medical applications. This article presents the design of a curved demonstrator named Fusillo, a Canted Cosine Theta Nb-Ti dipole magnet that is being developed at CERN, featuring a large aperture of 236 mm, a small bending radius of 1 m, a bending angle of 90$^{\circ }$, and multi-harmonic field correction, with a 3.61 T conductor peak field.

Analytical Evaluation of Dipole Performance Limits for a Muon Collider
/ Novelli, Daniel (U. Rome La Sapienza (main) ; INFN, Genoa) ; Bersani, Andrea (INFN, Genoa) ; Bottura, Luca (CERN) ; Caiffi, Barbara (INFN, Genoa) ; Fabbri, Siara (CERN) ; Farinon, Stefania (INFN, Genoa) ; Mariotto, Samuele (INFN, Milan ; Milan U. ; LASA, Segrate) ; Musenich, Riccardo (INFN, Genoa) ; Pampaloni, Alessandra (INFN, Genoa) ; Salmi, Tiina (Tampere U. of Tech.) et al.
Following the recommendation of the Updated European Strategy for Particle Physics, an International Muon Collider Collaboration has been formed and is currently studying the feasibility of a 10 TeV center-of-mass energy muon collider facility. Several technical challenges must be faced, mainly due to the limited muon lifetime at rest, 2.2 µs. [...]

FOCUS: fast Monte Carlo approach to coherence of undulator sources
/ Siano, M (Milan U. ; INFN, Milan) ; Geloni, G (European XFEL, Hamburg) ; Paroli, B (Milan U. ; INFN, Milan) ; Butti, D (CERN) ; Lefèvre, T (CERN) ; Mazzoni, S (CERN) ; Trad, G (CERN) ; Iriso, U (CELLS - ALBA, LLS) ; Nosych, A A (CELLS - ALBA, LLS) ; Torino, L (CELLS - ALBA, LLS) et al.
FOCUS (Fast Monte CarlO approach to Coherence of Undulator Sources) is a new GPU-based simulation code to compute the transverse coherence of undulator radiation from ultra-relativistic electrons. The core structure of the code, which is written in the language C++ accelerated with CUDA, combines an analytical description of the emitted electric fields and massively parallel computations on GPUs.

Assembly and Test Results of the RMM1a,b Magnet, a CERN Technology Demonstrator Towards Nb3Sn Ultimate Performance
/ Gautheron, Emma (CERN) ; Bordini, Bernardo (CERN) ; Campagna, Guillaume (CERN) ; Felice, Hélène (CERN) ; Fleiter, Jerome (CERN) ; Guinchard, Michael (CERN) ; Izquierdo Bermudez, Susana (CERN) ; Mugnier, Sylvain (CERN) ; Perez, Juan Carlos (CERN) ; Petrone, Carlo (CERN) et al.
As part of the High Field Magnet technology development carried out at CERN, demonstrators are under construction to explore the full potential of Nb 3 Sn. The Racetrack Model Magnet (RMM) is one of them, building upon the successful Enhanced Racetrack Model Coil (eRMC) eRMC1a magnet which reached 16.5 T peak field or 16.3 T bore field at 1.9 K. [...]
