The status of the FCC-ee optics tuning
/ van Riesen-Haupt, Léon (Ecole Polytechnique, Lausanne) ; Franchi, Andrea (ESRF, Grenoble) ; Faus-Golfe, Angeles (IJCLab, Orsay) ; Chance, Antoine (Paris, CEA) ; Dalena, Barbara (Paris, CEA) ; Järmyr Eriksson, Carl (CERN) ; Carli, Christian (CERN) ; Garcia Jaimes, Cristobal Miguel (Ecole Polytechnique, Lausanne) ; Shatilov, Dmitry (CERN) ; Musa, Elaf (DESY) et al.
With a circumference of approximately 91 km, the Future Circular electron-positron Collider, FCC-ee, aims for unprecedented luminosities at beam energies from 45.6 to 182.5 GeV. A major challenge is reaching its design performance in the presence of magnet misalignments and field errors. [...]

Review of MAD-X for FCC-ee studies
/ Simon, Guillaume (CERN ; IJCLab, Orsay) ; Faus-Golfe, Angeles (IJCLab, Orsay) ; van Riesen-Haupt, Léon (Ecole Polytechnique, Lausanne) ; De Maria, Riccardo (CERN) ; Pieloni, Tatiana (Ecole Polytechnique, Lausanne)
The design of the electron-positron Future Circular Collider (FCC-ee) challenges the requirements on optics codes (like MAD-X) in terms of accuracy, consistency, and performance. Traditionally, MAD-X uses a transport formalism by expanding the transfer map about the origin up to second order to compute optics functions and synchrotron radiation integrals in the TWISS and EMIT modules.

First FCC-ee lattice designs with Nested Magnets
/ Garcia Jaimes, Cristobal Miguel (Ecole Polytechnique, Lausanne, LPAP) ; van Riesen-Haupt, Léon (Ecole Polytechnique, Lausanne, LPAP) ; Seidel, Mike (Ecole Polytechnique, Lausanne, LPAP) ; Tomas, Rogelio (CERN) ; Pieloni, Tatiana (Ecole Polytechnique, Lausanne, LPAP)
The Future Circular Electron-Positron Collider (FCC-ee) represents a cutting-edge particle physics facility designed to further investigate the Z, W± and Higgs boson in addition to the top quark. The implementation of Nested Magnets (NMs) in the FCC-ee arc cells would maintain high luminosity and reduce its energy consumption. [...]

Resonant spin depolarization at the test facility KARA: overview of recent efforts
/ Blomley, Edmund (KIT, Karlsruhe) ; Müller, Anke-Susanne (KIT, Karlsruhe) ; Härer, B (KIT, Karlsruhe) ; Huttel, Erhard (KIT, Karlsruhe) ; Zimmermann, Frank (CERN) ; Keintzel, Jacqueline (CERN) ; Steinmann, Johannes (KIT, Karlsruhe) ; Gethmann, Julian (KIT, Karlsruhe) ; Ruprecht, Robert (KIT, Karlsruhe)
The Karlsruhe research accelerator KARA offers a setup to measure the beam energy with resonant spin depolarization. The depolarization is excited by the stripline kickers of the bunch-by-bunch feedback system and the resonant frequency is measured via change in Touschek lifetime. [...]

An Efficient Optimisation of a Burst Mode-Operated Fabry-Perot Cavity for Compton Light Sources
/ Mușat, Vlad (CERN ; Oxford U.) ; Cormier, Eric (LP2N, Bordeaux) ; Granados, Eduardo (CERN) ; Latina, Andrea (CERN) ; Santarelli, Giorgio (LP2N, Bordeaux)
The burst mode operation of a Fabry-Perot cavity (FPC) allows for the generation of a high-intensity photon beam in inverse Compton scattering (ICS) sources. The geometry and burst mode parameters of the FPC can be optimised to maximise the scattered photon flux. [...]
