Fast-neutron radiography and tomography using Associated Particle Imaging (API) Deuterium-Tritium (D-T) neutron generators are currently under investigation for various end-use applications within the NNSA mission space. Advancements to API D-T neutron generator technology are necessary to realize practical applicability to these end-use applications.  These advancements require higher neutron emission rates and improved timing and position resolution from an alpha detector.  Users of API D-T neutron generators would benefit directly from the advanced alpha detector potentially realized with this project.  This project is developing an alpha detector and a high-speed readout to measure the alpha particles emerging from the nuclear reaction between a tritium target and a deuterium source.
