The objective of this research is to develop new measurement capabilities for nuclear analytical techniques associated with the measurement of induced charged particle and/or gamma ray emissions during thermal and cold neutron beam irradiation. Nondestructive methods such as Neutron Depth Profiling (NDP) and Prompt Gamma Activation Analysis (PGAA) are well suited for applications in Li ion battery in-situ studies (NDP) and multi-elemental analysis (PGAA). The research will explore imaging of the induced charged particle and gamma ray emission, and develop image reconstruction techniques to obtain spatial distribution of the elemental composition based on spectral analysis of the emitted radiation. Much of the effort will be dedicated to developing and applying detection systems suitable for charged particle and spectral gamma ray imaging during neutron beam irradiation. The research is conducted at two neutron beam instruments at the NIST Center for Neutron Research (NCNR).
