Inspired by the production of NEG-coated vacuum chambers, this novel technique for high quality Nb/Cu cavities that can be used in FCC-ee has completed its first qualitative feasibility study.
Aimed at reducing the energy use of accelerator facilities, the Zero Power Tunable Optics project demonstrated the replacement of resistive electromagnets with permanent ones whilst retaining field strength adjustability.
Aimed at identifying solutions for the reuse rock excavated during tunnelling for future CERN colliders, this competition shortlisted four promising proposals.
A recent analysis, comparing the environmental impact of different proposed Higgs factories per physics output, concluded that the FCC-ee is the most sustainable design.
Optimised system designs for power efficiency, high efficiency klystrons, permanent magnets, renewable power… The linear collider projects are working to address power efficiency and reduce the environmental impact of the facilities.
