| Title | Photon stimulated desorption beamline at NSLS-II |

| Abstract | Understanding synchrotron induced gas desorption plays an important role in predicting vacuum behavior of accelerators. Investigations of new materials and coatings require careful study of their desorption yield for potential use in upgrading NSLS-II as well as other accelerator facilities. A beamline at NSLS-II, dedicated to the study of novel and proposed vacuum materials has been constructed and commissioned to advance further research into desorption behavior. The PSD of stainless steel, OFHC copper and NEG coated copper, some of which for use in the future Electron-Ion Collider at BNL, have been measured and will be presented. These newly established desorption rates will be used as inputs to advanced modeling tools such as MolFlow+ and SynRad+ for accurate predictions of vacuum behavior and design optimization. The existing layout and future plans for the beamline will be presented. |
