The Alignment of the Advanced Photon Source at Argonne National Laboratory

Currently the Advanced Photon Source (APS) is under construction at the Argonne National Laboratory. The APS is a 7-GeV synchrotron light source which will be used for basic research in material science, chemistry, physics, biology, and medicine to name a few of the participating disciplines. The commissioning phase for the APS is planned to start at the beginning of 1995. This paper describes the general parameters of the Advanced Photon Source, the required survey and alignment tolerances, and the alignment concept and instrumentation used to position storage ring beam components.
