Numerical calculation of the Lorentz force detuning and the pressure sensitivity for the HL-LHC crab cavity
/ Guillén-Hernández, T (CERN) ; Artoos, K (CERN) ; Calaga, R (CERN) ; Cano-Pleite, E (Carlos III U., Madrid) ; Capatina, O (CERN) ; Carra, F (CERN) ; Dassa, L (CERN) ; Turaj, K (CERN) ; Valverde-Alonso, N (CERN)
Crab cavities are fundamental components of the LHC upgrade in the framework of the HL-LHC project. These Radio Frequency cavities, operated at the appropriate frequency, ‘tilt’ the proton bunches to increase the luminosity at the collision points IP1 (ATLAS) and IP5 (CMS). [...]

Literature Review of Suspension Systems for Superconducting Elements
/ Piacentini, Luca (Latvia U., ISSP) ; Dassa, Luca (CERN) ; Perini, Diego (CERN) ; Ratkus, Andris (Latvia U., ISSP) ; Torims, Toms (Latvia U., ISSP) ; Uberti, Stefano (U. Brescia)
When designing suspension systems for superconducting elements, the primary challenge is to strike a balance between limiting the heat load to the cold mass and ensuring the proper mechanical resistance and/or stiffness of the system. This trade-off often leads engineers to choose from a limited set of materials and supporting architectures. [...]
