Abstract (D6.S4)

Completion of the design of the collider optics with new designs for collimation and extraction/dump insertions. The new layout imposes some in-depth changes in the overall configuration of the FCC-hh ring. The experimental straight sections have been reviewed since the version presented in the CDR, in terms of their geometry and the detail of the optical solutions. The technical straight sections have been deeply reviewed due to the change in length and the different functionalities associated with them. This entails new optical designs and detailed studies to validate their performance. The deliverables will include the new designs of the regular arcs and dispersion suppressors, the experimental straight sections, the beam dump and injection straight section, collimation straight sections and the RF and injection straight section.
