The Advanced Photon Source (APS) Upgrade will result in X-ray beams that are up to 500 times brighter than those generated by the original APS. But that’s only half the story. The upgrade team is also building seven new beamlines, constructing critical infrastructure to enable two more beamlines to be built, and updating many other experiment stations around the ring. 

Work on the beamlines is ramping up. One of the most visible recent projects has been the assembly of the Grand Tube at beamline 9-ID. The Grand Tube is a 70-foot-long enclosure that will enable a new X-ray technique called Coherent Surface Scattering Imaging (CSSI). This will allow scientists to image extremely small materials in three dimensions on a scale previously unattainable. 

The Grand Tube, weighing 100,000 pounds, arrived at Argonne in four sections and took three weeks to assemble. The video below shows the scale of the enclosure and the process of putting it together on the APS experiment floor.
