| Abstract Scope |
The damage caused by radiation in materials creates observable changes in the microstructure and subsequent properties. Knowing the changes in these material properties in response to different controlled radiation environments is important in various applications such as nuclear thermal propulsion or research reactors. These changes in structural defects can be rapidly identified by measuring various forms of vibrations or acoustic emissions emitted from the sample. These emissions are characteristic of the material and type of damage produced within. This research looks at the use of acoustic emission sensing to characterize damage in materials exposed to in-situ ion radiation experiments performed at the Tennessee Ion Beam Materials Laboratory. The experiments aim to identify differences in waveform characteristics of acoustic emission signatures caused by electronic and nuclear stopping of different ions at low and high energies. The results are compared to other in-situ acoustic emission experiments found in the literature. |
