Growth of Nb films on Cu for superconducting radio frequency cavities by direct current and high power impulse magnetron sputtering: A molecular dynamics and experimental study
/ Ghaemi, M (Helsinki Inst. of Phys.) ; Lopez-Cazalilla, A (Helsinki Inst. of Phys.) ; Sarakinos, K (Helsinki U. ; Royal Inst. Tech., Stockholm) ; Rosaz, G J (CERN) ; Carlos, C P A (CERN) ; Leith, S (CERN) ; Calatroni, S (CERN) ; Himmerlich, M (CERN) ; Djurabekova, F (Helsinki Inst. of Phys.)
The use of superconducting radio frequency (rf) cavities in particle accelerators necessitates that copper (Cu) surfaces are coated by thin niobium (Nb) films, predominantly synthesized by magnetron sputtering. A key feature of the rf cavities is that they exhibit a complex three-dimensional geometry, such that during Nb film growth vapor is not deposited on a flat substrate [...]

Experience on Series Production of the HL-LHC Superferric High Order Corrector Magnets
/ Statera, M (Milan U.) ; Prioli, M (Milan U.) ; Broggi, F (Milan U.) ; De Matteis, E (Milan U.) ; Imeri, L (Milan U.) ; Leone, A (Milan U.) ; Mariotto, S (Milan U. ; INFN, Milan) ; Paccalini, A (Milan U.) ; Pasini, A (Milan U.) ; Pedrini, D (Milan U.) et al.
INFN has developed at the LASA lab (Milano, Italy) the High Order (HO) corrector magnets for the High Luminosity-LHC (HL-LHC) project, which will equip the new interaction regions. All the HO correctors, from skew quadrupole to dodecapole, are based on a novel superferric design, never used so far in high energy colliders, which allows a relatively simple, modular, and easy way to construct a magnet.

Training-free performance of the wax-impregnated SuShi septum magnet
/ Barna, D (Wigner RCP, Budapest) ; Brunner, K (Wigner RCP, Budapest) ; Novák, M (Wigner RCP, Budapest) ; Borburgh, J (CERN) ; Atanasov, M (CERN) ; Lackner, F (CERN) ; Olvegård, M (Uppsala U.) ; Pepitone, K (Uppsala U.) ; Santiago Kern, R (Uppsala U.) ; Svanberg, C (Uppsala U.) et al.
In the framework of the Future Circular Collider Study a new septum magnet concept, nicknamed ‘SuShi’ has been developed, and a prototype was built at Wigner Research Center for Physics, and tested at the FREIA facility of Uppsala University in April 2023. The concept uses a canted cosine theta (CCT)-like superconducting magnet and a passive superconducting shield to create a zero-field and high-field region within its aperture. [...]

First considerations on the supporting structures of FCC-ee booster and collider in the arc regions

In 2022, the FCC Feasibility Study management mandated aworking group to analyse the best configuration of the FCC-ee tunnelin the arc regions, in view of the construction of a mock-up of thearc half-cell. One of the main and most challenging goals of thestudy, named FCC-ee Arc Half-Cell Mock-up Project, was toperform a preliminary investigation on the principles of supportingthe Short-Straight Sections and dipoles of the half-cells, both forthe booster and for the collider machines.
