Linac Coherent Light Source II (LCLS-II) – SLAC National Accelerator Laboratory Stanford University, Menlo Park, CA

LCLS-II is the upgrade of the Linac Coherent Light Source (LCLS) national user facility. LCLS is a powerful x-ray laser that enables exploration of atomic motion and changes in chemical bonds. The upgrade will add two new X-ray laser beams and expand the capacity for more instruments and research experiments. Berkeley Lab is leading the design and production of the injectors and undulators for the facility upgrade.
