Abstract
In the framework of an international collaboration, a 100 TeV hadron collider in a 100-km long tunnel is under study as a future circular collider beyond LHC at CERN. Its design is based on 16-T superconducting magnets cooled at 1.9 K by 10 cryoplants with a unit equivalent capacity of 100 kW at 4.5 K, up to 4 times larger than the present state-of-the-art. Half of the entropic refrigeration load is due to the synchrotron radiation produced by the high-energy proton beams and deposited on beam screens cooled between 40 and 60 K. This non-conventional thermal load distribution is an additional challenge for the cryogenic system. An engineering study on FCC-hh cryoplants is in progress with world-leader industries to define the preliminary conceptual design of industrial solutions and to confirm innovative technologies. The paper recalls the FCC-hh cryogenic requirements, presents the main results of Linde Kryotechnik study and highlights some identified R&D efforts.

Summary
The Future Circular Collider (FCC) study elaborates the design of the generation of highenergy particle physics instruments being hosted at CERN in the framework of an international collaboration to nurture the European Strategy for high energy particle physics. Different scenarios of circular colliders are currently examined and a hadron-hadron collider (FCC-hh) with a centre-of-mass energy of 100 TeV in a 100-km long tunnel is the baseline of the overall infrastructure for the on-going FCC study. Building such a FCC-hh machine requires key technology R&D program to select the most advanced superconducting magnet, cryogenic and accelerator technologies. The overall cryogenic layout is defined taking into account both the FCC infrastructure constraints (access points, surface/underground installations) and the non-conventional thermal load distribution.
