SRF technology

A superconducting radio-frequency accelerator cavity is mounted and connected to a cryocooler, cooling the cavity without the use of liquid helium. This new device could make it easier to produce high-average-power electron beams for industrial applications. Photo: Marty Murphy

Researchers demonstrate the cryogen-free operation of a superconducting radio-frequency cavity that might ease barriers to its use in societal applications.

From Forbes, Jan. 24, 2018: Fermilab will provide half of SLAC’s LCLS-II cryomodules, and Jefferson Lab in Newport News, Virginia, will provide the other half. Fermilab is located in Illinois, so the very first cryomodule that arrived at SLAC by truck last week made a hefty trip from Illinois to California – essentially making a trip across the whole of the U.S.
