The Advanced Light Source (ALS) is a third-generation synchrotron light source at Lawrence Berkeley National Laboratory. Built in 1993, the ALS serves over 40 beamlines and is one of the world’s brightest ultraviolet and soft X-ray light sources. The 196.8-meter circumference storage ring has an electron beam energy of 1.9 GeV. It supports experiments across various fields, including materials science, biology, chemistry, physics, and the environmental sciences. The ALS is upgrading to become a fourth-generation light source, adding a new accumulator ring and replacing the existing storage ring—the U.S. Department of Energy, Office of Science, Basic Energy Sciences program funds the ALS operation and its upgrade project.

SLAC National Accelerator Laboratory

SLAC is a scientific research center with a broad program in accelerator physics, astrophysics, atomic and solid-state physics, chemistry, biology, and medicine.

We concentrate on building and using large particle accelerators to probe the nature of molecules using X-ray light. We are also involved in experimental and theoretical research in elementary particle physics, astrophysics, and cosmology.

Laser Interferometer Gravitational-Wave Observatory (LIGO)

The Laser Interferometer Gravitational-Wave Observatory (LIGO) is leading the way in the new and exciting field of gravitational-wave astrophysics through the direct detection of gravitational waves predicted by Einstein’s General Theory of Relativity. LIGO’s multi-kilometer-scale gravitational wave detectors use laser interferometry to measure the minute ripples in the fabric of space-time caused by passing gravitational waves from cataclysmic cosmic sources, such as the mergers of pairs of neutron stars or black holes. LIGO consists of two widely separated detectors within the United States, in Hanford, Washington and Livingston, Louisiana.

LIGO is funded by the U.S. National Science Foundation (NSF), operated by the California Institute of Technology (Caltech) and the Massachusetts Institute of Technology (MIT), and is aided by collaborators from the over 80 scientific institutions world-wide that are members of the LIGO Scientific Collaboration (LSC).

The 2017 Nobel Prize in Physics has been awarded to three key players in the development and ultimate success of LIGO.
