Helium’s chilling journey to cool a particle accelerator
From SLAC, August 31, 2022: Fermilab researchers worked with a team of 20 operators and engineers at SLAC on cryogenics to build a helium-refrigeration plant to lower the LCLS-II accelerator to superconducting temperatures. Now, it only takes one and a half hours to make a superconducting particle accelerator at SLAC colder than outer space.
