Several thousand visitors tour Argonne National Laboratory every year. Most visitors are personally, professionally or academically interested in science, but the lay public is also welcome. Ideally, tours number about 15 people, but larger groups can be accommodated. Smaller groups and individuals can be added to tours already scheduled.

Tours are on a scheduled basis for ages 16 and over, and are usually scheduled in the morning from 9:00 a.m. until 11:30 a.m. or from 1:00 p.m. until 3:30 p.m. We require a list indicating the names and country of citizenship of all of the participants. All non-U.S. citizens need to fill out an access form for prior approval. Reservations are required.

The Argonne Information Center (AIC) is filled with more than 30 exhibits about science and technology and Argonne's current research programs.

The Advanced Photon Source (APS) produces x-ray beams of unprecedented brilliance, providing scientists from around the world with one of their best research tools. The highly penetrating light is ideally suited to a broad range of applications. Most of what we know about the three-dimensional arrangement of atoms in materials from elements to catalysts, from DNA to viruses, has come from x-ray research, and this newest x-ray device is taking that research to new levels. Users come from universities, industry, medical schools and other research institutions to conduct frontier science, studying materials of all types using the APS.

ATLAS -- The Argonne Tandem Linear Accelerator System (ATLAS) is the world's first superconducting facility capable of accelerating ions of all natural elements from hydrogen to uranium.

Engineering Research Exhibit has been developed to describe Argonne's historical role in the development of nuclear power and its current role in the resolution of key problems in the nuclear industry.
