Kathy Harkay was there at the start of the APS, working to determine the limits of what the machine could do. Now she’s working on upgrading the facility, and is looking forward to test-driving the new APS.
Prototypes of new superconducting magnets for the upgraded Advanced Photon Source were successfully lowered to their operating temperatures, far below freezing. These new magnets will help the APS generate more powerful X-rays more efficiently.
Laurent Chapon is Argonne’s Associate Laboratory Director for Photon Sciences, and director of the U.S. Department of Energy Office of Science’s Advanced Photon Source (APS).
Kasa and his colleagues are designing and building superconducting magnets for the upgraded Advanced Photon Source. They operate at far below freezing temperatures and help create world-leading levels of brightness for X-rays.
To provide X-ray beams that are both very bright and very tightly focused, an Argonne team had to create a new system of mirrors, lenses and equipment for the upgraded Advanced Photon Source.
