Proton cross-talk and losses in the dispersion suppressor regions at the FCC-hh / Rafique, Haroon ; Appleby, Robert Barrie (University of Manchester (GB)) ; Krainer, Alexander (Graz University of Technology (AT)) ; Langner, Andy Sven (CERN) ; Abelleira, Jose
Protons that collide at the interaction points of the FCC-hh may contribute to the background in the subsequent detector. Due to the high luminosity of the proton beams this may be of concern. [...]

Updates on the optics of the future hadron-hadron collider FCC-hh / Chance, Antoine ; Boutin, David Jean Henri ; Dalena, Barbara ; Holzer, Bernhard (CERN) ; Langner, Andy Sven (CERN) ; Schulte, Daniel (CERN)
The FCC-hh (Future Hadron-Hadron Circular Collider) is one of the three options considered for the next generation accelerator in high-energy physics as recommended by the European Strategy Group. The layout of FCC-hh has been optimized to a more compact design following recommendations from civil engineering aspects. [...]

Overview of design development of FCC-hh Experimental Interaction Regions / Seryi, Andrei (University of Oxford (GB)) ; Abelleira, Jose ; Cruz Alaniz, Emilia ; Van Riesen-Haupt, Leon ; Benedikt, Michael (CERN) ; Besana, Maria Ilaria (CERN) ; Buffat, Xavier (CERN) ; Burkhardt, Helmut (CERN) ; Cerutti, Francesco (CERN) ; Langner, Andy Sven (CERN) et al.
The experimental interaction region (EIR) is one of the key areas that define the performance of the Future Circular Collider. In this overview we will describe the status and the evolution of the design of EIR of FCC-hh, focusing on design of the optics, energy deposition in EIR elements, beam-beam effects and machine detector interface issues..
