Abstract Scope |
Accumulated radiation damage can substantially modify microstructure in nuclear materials. Realistic prediction of radiation effects requires understanding the interplay between electronic and atomic processes on defect dynamics. To assess irradiation resistance of nuclear materials, energetic ion beams are commonly used to create displacement damage. While charged particles are unique tools to study radiation response, the coupling of electronic energy dissipation to atomic processes has significant implications for using energetic ions to emulate neutrons. Moreover, ion-beam based analytical techniques are unique tools to characterize radiation effects. Ion beam analysis techniques (e.g., Rutherford backscattering spectrometry, nuclear reaction analysis, and time-of-flight elastic recoil detection analysis) coupled with electron microscopy and positron annihilation spectroscopy have been utilized to study defect formation and evolution in ceramics and metal alloys. The distinctive analyzing power and results from these methods have enhanced the understanding of non-equilibrium defect processes and contributes to the accelerated qualification of nuclear materials. |
