The Stanford Linear Accelerator Center, commonly known by its acronym SLAC, is one of the world's premier research facilities for high-energy physics and synchrotron radiation. It was established in 1962 and is located at Stanford University in Menlo Park, California.
History and Development
- 1962: SLAC was founded by Wolfgang K.H. Panofsky, who became its first director. The center was initially focused on particle physics experiments using the world's longest linear accelerator, which was completed in 1966.
- 1966: The linear accelerator, stretching 2 miles (3.2 kilometers), began operations. It was designed to accelerate electrons to nearly the speed of light to study particle interactions.
- 1974: SLAC scientists discovered the J/ψ particle, which was a significant discovery leading to the understanding of the charm quark, contributing to the development of the Standard Model of particle physics.
- 1980s - 1990s: Expansion into synchrotron radiation research began with the construction of Stanford Synchrotron Radiation Laboratory (SSRL), which provided intense X-ray beams for materials science, chemistry, biology, and other fields.
- 2008: SLAC was renamed to SLAC National Accelerator Laboratory to reflect its broader mission and the growing importance of its research beyond particle physics.
- 2009: The Linac Coherent Light Source (LCLS), the world's first hard X-ray free-electron laser, was commissioned, opening new avenues in ultrafast science.
Research and Facilities
- Particle Physics: The main accelerator has been used for numerous experiments, including the discovery of the tau lepton and the quark-gluon plasma.
- Synchrotron Radiation: SSRL and LCLS facilities offer advanced tools for structural biology, materials science, environmental science, and more.
- Advanced Computing: SLAC has a strong focus on computational science, supporting research in astrophysics, cosmology, and data science.
Notable Discoveries and Achievements
- Nobel Prizes in Physics have been awarded for discoveries at SLAC, including the development of the quark model and the discovery of the tau lepton.
- SLAC has been pivotal in advancing our understanding of the universe through its contributions to cosmology and particle physics.
