2016 | ANNUAL REPORT 67 chamber to air.This, and not being able to identify the irradiated area, prevented extensive mechanical properties measurements. Cursory micro-hardness measurements (Vickers) indicate that the irradiated areas may be harder than the native microstructure. Distributed Partnership at a Glance NSUF and Partners Facilities and Capabilities University of Wisconsin Tandem Accelerator Ion Beam Collaborators University of Illinois John Popovics (co-principal investigator), Paramita Mondal (co-principal investigator) University ofTennessee Chris Wetteland (co-principal investigator), Kurt Sickafus (co-principal investigator) University of Wisconsin JeffTerry (co-principal investigator) Oak Ridge National Laboratory Kevin Field (co-principal investigator) Future Activities Future goals are to expand the capabilities of the chamber so that multiple irradiations can be performed on a single target. Further investigation should examine changes in the mechanical properties. Figure 4. Mass Spectrum pre, during, and post irradiation using a Stanford Research Systems Residual gas analyzer. Irradiation begins at ~2 minutes and stops at ~4 minutes. An increase in the water signal is observed during the irradiation. Beam current used is ~80 nA.
