Description

This contribution presents FCC-hh operational schedule, turnaround cycle and availability goals. To maximize the physics output, the plan is to limit considerably the reserved time for maintenance and commissioning in the FCC schedule. The possibility of performing the annual maintenance stop in two months is discussed. FCC is designed to achieve about 50 % physics efficiency, which implies a strong dependence of integrated luminosity production on the turnaround time and injector chain performance. The challenges related to this target are analysed. Despite the increasing complexity of the FCC machine, the goal is to maintain the same operational availability achieved for LHC operation. This contribution identifies the key impact factors and systems based on LHC experience and illustrates possible solutions and areas for further studies to improve availability.
