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.

Mattia Checchin, a Ph.D. student from the Illinois Institute of Technology who is conducting his thesis research at Fermilab, has won first prize in the LINAC 16 student poster contest.
