Particle accelerators are made of structures called cavities, which impart energy to the particle beam, kicking it forward. One type of cavity is the superconducting radio-frequency, or SRF, cavity. Usually made of niobium, SRF cavities require extreme cold to operate. A Fermilab team developed a new way of cooling SRF cavities without liquid helium. The new system is easier to operate and simpler to construct.
