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.
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.
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.
In order to reduce the beam emittance by a large factor, the CLIC Collaboration has developed an innovative dipole magnet prototype and built a permanent magnet demonstrator
Two 90-mm Niobium-titanium (NbTi) double-aperture quadrupole magnets, also called MQYY in the LHC vernacular, have been developed and manufactured by the companies Elytt Energy and SigmaPhi under the QUACO project for the High-Luminosity LHC upgrades.
Uppsala University is upgrading its FREIA Laboratory, initially constructed for the ESS project, to test superconducting magnets and crab cavities for the HL-LHC
