Cryoplant
The superconducting part of the accelerator is cooled using liquid helium made in this cryoplant on the SLAC campus. The cryoplant cycles helium gas through series of systems to get it down to 2 kelvin (-456° Fahrenheit), at which point the helium is liquid. The liquid helium is then fed into cylindrical containers that surround the electron beamline, cooling the system down. The linear accelerator is expected to be cooled down by the end of April 2022.
