The objective of this research is to investigate boron carbide diode-based sensors applied to high spatialresolution neutron imagers. The approach is to experimentally and theoretically investigate theoperational parameters and spatial resolution enhancement techniques required for this purpose. Thefour spatial resolution enhancement techniques to be investigated include threshold discrimination,density gradient, fast logic, and columnar sensor medium techniques. Each of these enhancementtechniques will be investigated for feasibility and effectiveness. Boron carbide diode sensors will also becharacterized experimentally with respect to related operational parameters for these spatial resolutionenhancement techniques. The combination of these results will provide a basis for the development of astate-of-the-art neutron imager. The boron carbide will also be tested through direct coupling with TimepixQTPX-262k to test its functionality and improvement of current state of the art techniques utilizingestablished front end electronics and signal processing methods.
