SLAC National Accelerator Laboratory (SLAC), formerly known as the Stanford Linear Accelerator Center, is a federally funded research and development center located in Menlo Park, California, United States. It was established in 1962 and is owned by the U.S. Department of Energy. SLAC is primarily focused on research in particle physics, astrophysics, and synchrotron radiation. It operates several particle accelerators, including the Stanford Linear Accelerator (SLAC), which is one of the longest linear accelerators in the world. SLAC also hosts a variety of research facilities, including the Linac Coherent Light Source (LCLS), a free-electron laser that produces extremely bright and short X-ray pulses. The laboratory is home to a diverse community of scientists, engineers, and technicians who conduct cutting-edge research and collaborate with institutions around the world.
