The Advanced Photon Source
a U.S. Department of Energy Office of Science User Facility


The Advanced Photon Source delivers world-class science and technology by operating an outstanding synchrotron radiation research facility accessible to a broad spectrum of researchers in order to further the U.S. DOE Office of Science mission to "...transform our understanding of nature and to advance the energy, economic, and national security of the United States."

Argonne National Laboratory

National Scientific User Facilities

Propelling discovery

Argonne is home to five national user facilities, which enable scientific users from universities, national laboratories, industry and federal agencies to carry out experiments and pursue groundbreaking discoveries that would otherwise not be possible.

Advanced Photon Source

The Advanced Photon Source (APS) at the U.S. Department of Energy’s Argonne National Laboratory provides ultra-bright, high-energy storage ring-generated X-ray beams for research in almost all scientific disciplines.

Argonne Leadership Computing Facility

The Argonne Leadership Computing Facility provides supercomputing capabilities to the scientific and engineering community to advance fundamental discovery and understanding in a range of disciplines.

Argonne Tandem Linear Accelerator System

The prime national facility for nuclear structure research. The Argonne Tandem Linear Accelerator System (ATLAS) is the world’s first superconducting linear accelerator for heavy ions at energies in the vicinity of the Coulomb barrier.

Atmospheric Radiation Measurement Research Facility – Southern Great Plains

ARM is the world’s premier ground-based observations facility advancing atmospheric research.

Center for Nanoscale Materials

The Center for Nanoscale Materials (CNM) at Argonne National Laboratory is a premier user facility providing expertise, instrumentation and infrastructure for interdisciplinary nanoscience and nanotechnology research.
