The National User Facilities are a set of large-scale scientific facilities maintained by the U.S. Department of Energy, Office of Science,[1] whose roles are to provide the scientific community with world-leading scientific instruments to enable research. These facilities are generally free to use, and are open to scientists from all over the world, usually through the submission and evaluation of research proposals.

As of 2020, there are 26 such facilities.

Light sources

The light sources are synchrotron or x-ray free electron laser facilities that provide users with x-ray beams for a variety of scattering, spectroscopy, and imaging experiments. These facilities accommodate tens of beamlines running in parallel. Their 2000–5000 users per facility perform experiments each year.

Neutron sources

The neutron sources are spallation sources or reactors that provides users with neutron beams for a variety of experiments.

Super computers

The super-computing facilities are made available to the users to perform high intensity calculations. As of November 2019, four of the top ten super computers worldwide were hosted by a national user facility [2] ( Summit, Sierra, Trinity and Lassen.)
