SLAC Cryogenic Building 905

SLAC is a world-leading multi-purpose laboratory that explores frontier questions in photon science, astrophysics, particle physics, and accelerator research. In April 2016, SLAC announced that construction had begun on LCLS II. This upgrade entails the installation of a new unique x-ray laser and Cryoplant refrigerator—a powerful chilling plant containing compressors, pumps, and helium needed to keep the new laser at -456 degrees Fahrenheit (about the same temp as outer space). This upgrade will allow the new laser to fire 8,000 times faster, 10,000 times brighter, and at up to a million pulses per second. OEG will be assisting SLAC by installing remaining electrical in the Cryoplant refrigerator (Building 905). Once this project is complete, SLAC will be able to take x-ray science to the next level, and will open the door to a whole new range of studies advancing our ability to develop transformative technologies for the future including novel electronics, life-saving drugs, and innovative energy solutions.
