Making a sustainable future accelerator facility requires much more than reducing its energy consumption, it demands a direct quantification of the ecological footprint from start to end

Although permanent magnets can significantly reduce the energy consumption of accelerators, their use of rare earths requires best practices, as discussed by experts at the latest I.FAST workshop.

Through ingenious kinetic energy recycling in combination with a multi-turn acceleration concept, electric power can be saved while, at the same time, high-power particle beams can be provided.

With a funding of up to 200 kEUR each, the projects will contribute to improve the sustainability of particle accelerator technologies.

The CLIC collaboration is moving towards its technical design report.

To be renewed next summer, I.FAST project’s yearly student challenge explored environmental and societal applications of accelerator technology.

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.
