HPCAT-Upgrade: Progress, Updates and First Results

ORAL

Abstract

In concurrence with the recent upgrade undertaken by the Advanced Photon Source, HPCAT has undertaken an extensive upgrade of beam delivery optics, front-end components and end-stations. The 21/25 revolver undulator offers the flexibility of maximining flux at certain key energies or alternately, a large range of energies that can be accessed. The new MBA lattice offers world-leading emittance, higher brightness and coherence without large changes in flux and brightness. These two factors influence the trajectory of extreme conditions science at HPCAT, and all the upgrade plans we have made incorporate optimizing our capabilities to take full advantage of the new source. The recent workshop where we challenged our users and partners to look ahead and plan has resulted in a newfound energy and enthusiasm /1/. A total of five end-stations are planned to become available at the end of our upgrade activities. We have opted to roll out the end-stations in a systematic manner and three of them are currently transitioning from commissioning to user activities. We are excited to present our progress report and update the community on the first results which benchmark the higher brightness, coherence and smaller focus. This talk will also discuss how the community at large can optimize their experimental plans to leverage these capabilities.
