Argonne National Laboratory


Argonne’s Physics Division is organized into four research groups, which share knowledge and expertise to create a program of multidisciplinary nuclear physics research that makes full use of the division’s facilities. This program initiates collaborative projects that yield new insights into the core of matter.

Accelerator Development

Our accelerator development group conducts a broad range of accelerator R&D to advance technologies for future DOE facilities and other applications. The R&D program specializes in RF superconductivity for accelerators and is a recognized world leader in the application of this technology to ion accelerators.

Low Energy Physics (LEP)

Low energy nuclear physics research concerns itself with understanding the structure and stability of the nuclei in the atoms that make up the world around us, as well as the reactions which formed them in the cosmos.

Medium Energy Physics (MEP)

The goals of Argonne’s Medium Energy Physics group involve testing our understanding of the structure of hadrons and the structure of nuclei, and developing and exploiting new technologies for high-impact applications in nuclear physics, tests of fundamental symmetries and other national priorities.


Theoretical research in Argonne’s Physics Division addresses a broad range of problems involving the structure and dynamics of hadrons and nuclei. There is a strong emphasis on comparison to data provided by experimental groups at Argonne and at other facilities around the world.
