Improved CERN LHC layout and aperture models / Lampaki, Syrmatenia (Aristotle University of Thessaloniki (GR))
Aperture models are of fundamental importance to design machine optics configurations and predict machine performance. They are also essential to detect design flaws during the engineering and construction phase, and essential to steer alignment campaigns and optimize operational scenarios. [...]

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. [...]

Status of the synchrotron radiation studies in the interaction region of the FCC-ee / André, Kévin (CERN) ; Holzer, Bernhard (CERN) ; Boscolo, Manuela (Frascati)
The FCC-ee is a proposed high-luminosity circular electron-positron collider which will have beam energies spanning from 45.6 to 182.5 GeV, and will radiate up to 50 MW of synchrotron radiation power per beam. The lattice design upstream of the interaction point is based on weak dipoles and long straight sections combined with a 30 mrad crossing angle. [...]

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. [...]

High-resolution bunch profile measurements for enhanced longitudinal beam diagnostics / Brischetto, Ylenia (CERN) ; Timko, Helga (CERN) ; Argyropoulos, Theodoros (CERN)
Efficient operation of the Large Hadron Collider (LHC) relies on accurate longitudinal beam measurements to diagnose beam instabilities and verify the correctness of bunch-shaping techniques. To achieve this goal, a diagnostic system was developed to perform high-resolution measurements of longitudinal bunch profiles. [...]

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. [...]

ATF2-3 hardware upgrade and new experimental results to maximize luminosity potential of linear colliders / Faus-Golfe, Angeles (IJCLab, Orsay) ; Aryshev, Alexander (KEK, Tsukuba) ; Lyapin, Alexey (Oxford U.) ; Kruchinin, Konstantin (KEK, Tsukuba) ; Terunuma, Nobuhiro (KEK, Tsukuba) ; Fuster-Martinez, Nuria (Valencia U., IFIC) ; Burrows, Philip (Oxford U.) ; Mazzoni, Stefano (CERN) ; Okugi, Toshiyuki (KEK, Tsukuba) /ATF2 Collaboration
The ATF2-3 beamline is the only facility in the world for testing the Final Focus Beamline of linear colliders and is essential for the ILC and the CLIC projects. A vertical electron beam size of 41 nm (within 10% of the target), a closed-loop intra-bunch feedback of latency 133 ns, and direct stabilization of the beam position at the Interaction Point to 41 nm (limited by IP BPM resolution) have all been achieved at ATF2.

Tail population studies in the CERN Proton Synchrotron / Bozatzis, Miltiadis (Aristotle U., Thessaloniki ; CERN) ; Asvesta, Foteini (CERN) ; Bartosik, Hannes (CERN) ; Huschauer, Alexander (CERN) ; Lasheen, Alexandre (CERN) ; Maclean, Ewen (CERN) ; Prebibaj, Tirsi (CERN) ; Van Goethem, Wietse (CERN)
The beam quality in terms of the transverse beam profiles from the CERN injectors plays a crucial role for the luminosity production at the LHC. Transverse tails beyond a Gaussian distribution have been observed in all the LHC injectors and efforts to optimize them are ongoing, as they can perturb operations due to large losses at LHC injection.
