In May 2002, The Advanced Photon Source was reorganized into three
divisions: the Accelerator Systems Division (ASD), the APS Engineering Support
Division (AES), and the X-Ray Science Division (XSD). Parts
of the former User Program Division (UPD) were incorporated into
XSD, while other parts were incorporated into AES.
- APS Engineering Support
The APS Engineering Support Division serves the mission and goals of the APS by providing integrated, facility-wide engineering and technical services to the Accelerator Systems and X-ray Sciences divisions and to the APS user community.
- Accelerator Systems Division
The Accelerator Systems Division provides engineering and physics support for the Advanced Photon Source.
- X-ray Science Division
The X-ray Science Division develops and builds state-of-the-art synchrotron radiation instrumentation and uses it in a safe and environmentally sound manner, to conduct world-class research at the forefront of science and technology.
