The advanced photon source (APS), 7 GeV electron Storage Ring is designed to be a major national user facility providing high-brilliance x-ray beams. At completion, APS will have 35 bending magnet (BM) beamlines and 35 insertion device (ID) beamlines. A typical x-ray beamline at APS comprises of a front end (FE) that confines the beam; a first optics enclosure (FOE) which houses optics to filter and monochromatize the beam; and beam transports, additional optics, and the experiment stations. This paper describes in some detail the steps involved in the process of commissioning experimental stations and the implementation of the ALARA at each step.
