X-Ray Light Sources

Advanced Light Source (ALS)

at Lawrence Berkeley National Laboratory

The ALS is one of the world's brightest sources of high-quality, reliable vacuum-ultraviolet light and soft X-rays, enabling a wide variety of scientific disciplines.

Advanced Photon Source (APS)

at Argonne National Laboratory

The APS is one of only four third-generation, hard x-ray synchrotron radiation light sources in the world, which has brought about new discoveries in a wide range of scientific fields.

Linac Coherent Light Source (LCLS)

at SLAC National Accelerator Laboratory

The LCLS is the world’s first hard x-ray free electron laser facility capable of producing x-rays that are both very intense and clumped into ultrafast pulses.

National Synchrotron Light Source II (NSLS-II)

at Brookhaven National Laboratory

The NSLS-II is a state-of-the-art synchrotron light source which allows for scientists to probe the fundamental properties of matter, paving the way to new scientific discoveries and innovations.

Stanford Synchrotron Radiation Light Source (SSRL)

at SLAC National Accelerator Laboratory

The SSRL produces intense x-rays as a resource for researchers to study our world at the atomic and molecular level, allowing for research and advances in energy production, environmental remediation, nanotechnology, new materials and medicine.
