Development of a Field Emission Electron Gun for Low Energy Electron Cooling / Tranquille, Gerard (CERN) ; Cenede, Jean (CERN) ; Galante, Bruno (CERN ; PSI, Villigen) ; Welker, Elisabeth-Sena (CERN ; Vienna, Tech. U.)
The use of carbon nanotubes (CNT) as a cold electron source for a low energy electron cooler has been studied in detail. To fully characterise different CNT arrays (conditioning process, emitted current, lifetime) and to investigate the optimum electrical configuration of the source to be used in an electron gun, a cold cathode test bench (CCTB) has been set up.

Progress in the design of the future circular collider FCC-ee interaction region / Boscolo, Manuela (Frascati) ; Frasca, Alessandro (CERN) ; Novokhatski, Alexander (SLAC) ; Ciarma, Andrea (Frascati) ; Lechner, Anton (CERN) ; Ilg, Armin (Zurich U.) ; Di Pasquale, Enrico (Frascati) ; Palla, Fabrizio (INFN, Pisa ; CERN) ; Bosi, Filippo (INFN, Pisa) ; Fransesini, Francesco (Frascati) et al.
We report on the latest developments for the FCC-ee interaction region design that represents a major challenge for the collider, which has to achieve extremely high luminosity over a wide range of centre-of-mass energies. The FCC-ee will host four experimental apparatuses. [...]

Secondary beam line efficiency studies at the CERN PS East Experimental Area / Parozzi, Elisabetta (CERN) ; Banerjee, Dipanwita (CERN) ; Baratto Roldan, Anna (CERN) ; Bernhard, Johannes (CERN) ; Brugger, Markus (CERN) ; Charitonidis, Nikolaos (CERN) ; Dyks, Luke (CERN) ; Gatignon, Laurent (CERN) ; Goillot, Alice (CERN) ; Jebramcik, Marc (CERN) et al.
The East Area at the Proton Synchrotron has undergone extensive renovations, marking a significant milestone in its more than 55-year history as one of CERN’s enduring facilities for experiments, beam tests, and irradiation. This facility, which serves over 20 user teams for about 200 days annually, now boasts an enhanced infrastructure to cater to future beam test and physics requirements. [...]

Vertical Spin build-up due to Vertical Offset in Quadrupoles and Horizontal Betatron Oscillations / Cilento, Vera (CERN) ; Carli, Christian (CERN)
Many proposals to measure a possible small Electric Dipole Moment (EDM) of charged particles are based on the magic energy concept. Without EDM and for a ring without imperfections, an initial longitudinal polarization of a bunch is maintained in electro-static bendings by operation at a particular energy called the magic energy.

Optics for Landau Damping with Minimized Octupolar Resonances in the LHC / Wenninger, J (CERN) ; Solfaroli, M (CERN) ; Nissinen, T (CERN) ; Hostettler, M (CERN) ; Horney, S (CERN) ; Chudoba, F (CERN) ; Tomás García, Rogelio (CERN) ; Carlier, Felix (CERN) ; Deniau, Laurent (CERN) ; Dilly, Joschua (CERN) et al.
Operation of the Large Hadron Collider (LHC) requires strong octupolar magnetic fields to suppress coherent beam instabilities. The amplitude detuning that is generated by these octupolar magnetic fields brings the tune of individual particles close to harmful resonances, which are mostly driven by the octupolar fields themselves.

Periodicity five lattice proposal for a cpedm prototype ring / Cilento, Vera (CERN) ; Carli, Christian (CERN)
The community studying facilities to measure a possible Electric Dipole Moment of a charged particle (cpEDM) in a storage ring agreed that a Prototype Storage-Ring (PSR) is required as intermediate step to address critical questions, gain experience and rule out showstoppers. In what follows, a new lattice proposal of the PSR with a periodicity five is described and spin tracking simulations are shown. [...]

Derivation and interpretation of parameters describing betatron mismatch and chromaticity / Carli, Christian (CERN) ; Skoufaris, Kyriacos (CERN)
Expressions to quantify betatron mismatch and chromatic effects are frequently used in accelerator physics, but their derivations are not given in standard text books, making their interpretation difficult. First parameters describing betatron mismatch are introduced using normalization with respect to reference Twiss parameters describing a lattice. [...]

Analysis of the Leakage Events in the Thermal Shield Cooling Pipes of the ITER Magnet System / Sgobba, Stefano (CERN) ; Santillana, Ignacio Aviles (CERN) ; Celuch, Michal (CERN) ; Crouvizier, Mickaël (CERN) ; Perez Fontenla, Ana Teresa (CERN) ; Castro, Enrique Rodriguez (CERN) ; Mitchell, Neil (Euratom, St. Paul Lez Durance) ; Koizumi, Norikiyo (Euratom, St. Paul Lez Durance) ; Pearce, Robert (Euratom, St. Paul Lez Durance) ; Worth, Liam (Euratom, St. Paul Lez Durance) et al.
The ITER Thermal Shields (TS) consist of actively cooled stainless steel panels. Their role is to minimise the radiation heat load from warm components, such as the Vacuum Vessel (VV) and the cryostat, hence contributing to insulating the magnet system operating at 4.5 K. [...]

FCC-ee Lattice Design / Keintzel, Jacqueline (CERN) ; Abramov, Andrey (CERN) ; Benedikt, Michael (CERN) ; Hofer, Michael (CERN) ; Hunchak, Patrick (Saskatchewan U.) ; Oide, Katsunobu (CERN) ; Raubenheimer, Tor (SLAC) ; Tomás García, Rogelio (CERN) ; Zimmermann, Frank (CERN)
Within the framework of the Future Circular Collider Feasibility and Design Study, the design of the electron-positron collider FCC-ee is being optimised, as a possible future double collider ring, currently foreseen to start operation during the 2040s. FCC-ee is designed to operate at four different energy stages, allowing for precision measurements: from the Z-pole up to above the ttbar-threshold. [...]

Simulations of beam dynamics and beam lifetime for the prototype EDM ring / S Siddique (Darmstadt, GSI ; Aachen, Tech. Hochsch.) ; Lehrach, A (Aachen, Tech. Hochsch. ; Julich, Forschungszentrum) ; Pretz, J (Julich, Forschungszentrum) ; Carli, C (CERN) /JEDI Collaboration ; CPEDM Collaboration
The matter-antimatter asymmetry may be explained through CP-violation by observing a permanent electric dipole moment (EDM) of subatomic particles. An advanced approach to measure the EDM of charged particles is to apply a unique method of "Frozen spin" on a polarized beam in a storage ring. [...]
