Logistics is of great importance for the construction, assembly and operation of FCC. During set-up of LHC, logistics already proved to be a key factor. In respect of the size of FCC, logistics is increasing its significance. New concepts, methods and analytics for logistics, supply chain and transport concepts will have a direct impact on the estimation of the feasibility and costs of the...

Following the update of the European strategy in particle physics, CERN has undertaken an international study of possible future circular colliders beyond the LHC. The study considers several options for very high-energy hadron-hadron, electron-positron and hadron-electron colliders.

From the cryogenics point of view, the most challenging option is the hadron-hadron collider (FCC-hh) for... -

The Nelium concept is a novel approach for highly efficient refrigeration in the temperature range from 25 to 65 K, making it a promising candidate for the cooling of the FCC-hh beam screens. The concept uses a cycle with turbo compressors, which have higher efficiencies compared to classical screw compressors. To achieve acceptable capital cost, a mixture of neon and helium is used which...

Different scenarios of circular colliders are examined and a 100 TeV hadron collider in a 100 km long tunnel is the baseline of the overall infrastructure for the FCC study. Building such a machine requires the development of large unit-capacity cryogenic infrastructures (50 to 100 kW equivalent at 4.5 K) to cool down superconducting accelerator components. The cooling requirements are...

The Future Circular Collider (FCC), with of about 86 km circumference, will be the largest particle accelerator ever constructed. Such a scale entails numerous problems, many of which have never been faced before. One of them is a considerable growth in the length of cryogenic distribution lines. In case of the FCC the maximum length for the distribution line is considered as 8.4 km, what is...

This contribution presents the first version of the FCC-hh operation schedule and updates estimates on collider turn around cycle. The operational schedule shows planned time for physics operations and maintenance during collider life cycle. The schedule meets requirements for time reserved for physics production. However, this considerably limits the time reserved for maintenance and this...

The achievable level of availability will be one of the main performance indicators for the next generation of particle accelerators. Studies are ongoing for the FCC to model future operation of the collider based on LHC experience. The software ELMAS is used for modelling system fault trees and simulate the achievable integrated luminosity production as a function of different operational...
