| Abstract | 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. This is an importantinput needed for the choice of the best configuration of therelative placement of the booster with respect to the collider. Thestructural stiffness, mass and stability of the supportingstructures must be optimized to minimize the vibrationstransmitted/transferred to the magnetic system of the acceleratorsby elements such as pumps, water cooling system, beamthermomechanical stresses, powering elements, etc. To perform thestudy, tools such as CAD software, FEM and analytical techniqueswere employed. This paper summarizes the preliminary design conceptsand the results of the simulations performed. |
