Michael Moore

PhD Candidate

Biography

Michael Moore is a Doctoral Candidate in the Radiation Instrumentation Research Group in the Department of Nuclear Engineering at the University of Tennessee. He is interested developing and characterizing thermal neutron imaging instrumentation for high spatial resolution. His recent work has focused on evaluating the imaging abilities of microstructured multicore scintillating fibers at international neutron scattering facilities. He has worked as a detector developer at Spallation Neutron Source and as a nuclear security modeling intern at Oak Ridge National Laboratory. Prior to his graduate studies, Michael was undergraduate DHS nuclear forensics fellow at Penn State, where he received his B.S. in Nuclear Engineering.


Research

High resolution neutron imaging is an essential tool used for fundamental characterization of novel X-ray opaque microstructures. Currently, advanced neutron scattering facilities enable users to image materials with state-of-the-art neutron radiography spatial resolutions of approximately 10-20 microns. However, continued progress towards micron resolution is limited by the intensity and the linearity of available thermal neutron fluxes. This places an emphasis on increasing neutron conversion/detection efficiency while maintaining the spatial accuracy of the projected radiograph. This research progresses the development and experimental evaluation of microstructured 6Li glass SCIntillating FIber (SCIFI) for a new generation of higher resolution neutron radiography, as well as related applications to other scintillation-based imaging instruments, at international neutron science facilities.
