    A Computational Evaluation Of Neutron Capture Efficiency In Plastic Scintillators
    (2016-10-05) Schmitz, Ryan; Poehlmann, David-Michael; Rogers, Hannah; Barker, D'Ann; Cushman, Priscilla
    A Monte Carlo study using GEANT4 was performed on the neutron capture efficiency rates achieved by Gd-loaded plastic scintillators. A "deposition efficiency" parameter was defined as the percentage of incident neutrons which were captured in the Gd-loaded scintillator, and whose emitted gammas deposited energy above a certain threshold in a larger layer of plastic scintillator. Deposition efficiency curves were collected for varying thresholds and Gd concentrations, and the results are discussed here.
