The LCLS-II Cryoplant (center) purifies and chills liquid helium to minus 456 degrees Fahrenheit and pumps it through pipes to cryomodules below ground, where it cools the superconducting accelerator to an operating temperature of 4.5 kelvins.
A synchrotron is a type of particle accelerator that produces intense beams of light. Researchers use these beams to peer deep beneath the surfaces of things and explore a wide range of scientific phenomena.
