The Department of Energy is responsible for the operation of the Advanced Photon
Source, a light source user facility at the Argonne National Laboratory. The facility was,
until recently, operated for the Department by the University of Chicago. It is currently
operated by UChicago Argonne, LLC. Using x-ray beams from the Advanced Photon
Source, scientists conduct leading-edge research in areas such as material science,
biology, physics and chemistry. The Advanced Photon Source was completed in 1995 at
a cost of $467 million, and it was constructed to operate at an optimal capacity of 70
beam lines. Each beam line provides high intensity x-rays for research in almost all
scientific disciplines for government, academia and the private sector. The annual
operating budget of the facility is about $90 million, and the Department's Argonne Site
Office administers the contract for Laboratory operations.
