Update on Mechanical Design of a Cos theta 16-T Bending Dipole for the Future Circular Collider

After the large hadron collider (LHC), a higher energy range must be explored to address the open questions in particle physics. A new generation of colliders will be necessary, able to accelerate both leptons and hadrons to energy higher than previous machines. The EuroCirCol European collaboration, in the framework of the future circular collider (FCC) project, has the aim to provide a design for a hadron collider that is able to accelerate protons to 50 TeV in a 80-100 km circumference tunnel. One of the most challenging task is the design of the bending dipole, which must be able to produce magnetic field as high as 16 T. In this paper, the state of art of the cos θ option for the 16 T dipole for FCC is presented. In particular, the mechanical design will be described, showing that promising solutions have been found.
