Development Of A Mixed-Radiation Directional Rotating Scatter Mask Detection System, Bryan V. Egner Mar 2019

Development Of A Mixed-Radiation Directional Rotating Scatter Mask Detection System, Bryan V. Egner

Theses and Dissertations

Previous work demonstrated gamma-ray directional detection through the integration of a radiation detection system and an additively manufactured rotating scatter mask (RSM). This work advances the RSM directional detection system through improvements in the system's design, validation of a new scatter mask, and the novel ability to directionally detect both neutrons and gamma rays, a desirable feature for many nuclear safeguard and counterproliferation applications. The mixed-radiation RSM system developed for this research utilized the Spartan I mask design coupled with a 1" EJ-309 liquid scintillator. A GEome-try ANd Tracking (Geant4) model is developed and quantitatively compared to experimental measurements ...
