SLAC Job Postings

SLAC National Accelerator Laboratory is one of 17 Department of Energy (DOE) National Laboratories. Operated by Stanford University on behalf of the DOE, SLAC develops and operates some of the world’s premier science facilities, including the first hard X-ray free-electron laser. Researchers from SLAC and other premier institutions around the world use our facilities to investigate some of the most exciting and important problems facing our society in areas such as clean energy, environmental science, biomedicine, and advanced materials.

SLAC’s free electron laser is powered by a superconducting linear accelerator which relies on cryogenic support, including two 18 kW at 4.5 K cryogenic plants, providing a total refrigeration capacity of 8 kW at 2.0 K. Commissioning of the cryoplant and a superconducting linear accelerator was completed in 2023, and the system recently transitioned to operation.
