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.
From SLAC, Jan. 31, 2017: A full kilometer of SLAC’s historic linac has been stripped of all its equipment. Over the next two years it will be re-equipped with new technology to power an X-ray laser, LCLS-II. Fermilab and Jefferson Lab are building the cryomodules for its superconducting portion.
From Cold Facts, April 20, 2016: Fermilab’s work on LCLS-II is highlighted in a round-up of cryogenic facilities at national laboratories.
