Advanced Photon Source (APS)

9700 South Cass Avenue Lemont IL 60439
The Advanced Photon Source (APS) at the U.S. Department of Energy's Argonne National Laboratoryprovides this nation's (in fact, this hemisphere's) brightest storage ring-generated x-ray beams for research in almost all scientific disciplines. These x-rays allow scientists to pursue new knowledge...

Booster Synchrotron

Electrons are injected into the booster synchrotron, a racetrack-shaped ring of electromagnets, and accelerated from 450 MeV to 7 billion electron volts (7 GeV) in one-half second. (By comparison, the electron beam that lights a TV screen is only 25,000 electron volts.) The electrons are now...

Experiment Hall & Beamlines

The ratchet-shaped radiation-shielding wall between the APS storage ring and the experiment hall serves as a line of demarcation. Thirty-five "sectors" are marked on the experiment hall floor. Each of these sectors comprises at least two x-ray beamlines, one originating at a bending magnet in the...

Insertion Devices & Brilliance

Synchrotron storage rings optimized for insertion devices (photo below) are called "third-generation" light sources. Some, like the Advanced Light Source in California and the SuperACO in France, provide radiation in the ultraviolet/soft x-ray part of the spectrum. The 7-GeV APS and its sister...

Kansas City National Security Campus

14520 Botts Road DOE Kansas City National Security Campus Kansas City MO 64147
The DOE Kansas City National Security Campus (KCNSC) is a multi-mission facility focus on engineering design, manufacturing, and testing of National Security products for government agencies, national laboratories, universities and U.S. industry. The facility focuses on low volume manufacturing,...

Linear Accelerator

Producing brilliant x-ray beams at the APS begins with electrons emitted from a cathode heated to ~1100° C. The electrons are accelerated by high-voltage alternating electric fields in a linear accelerator (linac; photo below). Selective phasing of the electric field accelerates the electrons to...

LOMs & Beamlines

In designing the experiment hall, the APS benefited from the experiences of researchers who had carried out experiments at other synchrotron facilities. One lesson learned was the need for adequate user laboratory and office space. The APS User Organization opted for laboratory/office modules (or...

The Electron Storage Ring

The 7-GeV electrons are injected into the 1104-m-circumference storage ring, a circle of more than 1,000 electromagnets and associated equipment, located in a radiation-proof concrete enclosure inside the experiment hall, which is large enough to encircle Chicago's U.S. Cellular Field. A powerful...
