The availability and safety of the Future Circular Collider (FCC) are critical factors for its operation. To enhance these parameters cost-effectively, the FCC Robotic System (FCCRS) has been conceived and it is under development during the last years. The FCCRS comprises a Remote Maintenance and Inspection System (RMIS) and a Survayance and Emergency Shuttle (SES). This system will...

To reach integrated luminosity goals, the FCC-ee must be operational for minimum 80% of the scheduled 185 physics days each year. For comparison, the LHC achieved 77% in Run 2, 2016-2018. There are additional challenges in operation and maintenance of the FCC-ee due to its scale, complexity and ambitious technical objectives. Availability is therefore a significant risk to physics...

At this stage of the feasibility study of FCC, few challenges were identified, and the electrical network has a role to play in improving them.
Indeed, the study highlighted the need to use as little space as possible: on surface sites to limit the environmental impact, but underground as well to limit the civil engineering cost. In this sense, the electrical network is designed to reduce...

The talk provides the latest advancements in evaluating optimal powering solutions for the FCC-ee.
To achieve a global optimum which balances Capital and Operation Expenditures (CAPEX and OPEX) a holistic approach is needed. Several equipment designs such as cables, power converters, cooling and ventilation systems, magnet, and alcoves volumes are tightly related and CAPEX+OPEX...
