Title: Final report for the DOE/NA22 project, Physics of Scintillator Nonproportionality

Abstract

The energy resolution of current scintillators is known to be limited by the adverse impact of light yield nonproportionality. This effort aims to advance the understanding of the physics underlying nonproportionality sufficiently to enable breakthrough performance, by achieving energy resolution beyond the present limit of 2.5% at 662 keV. While we have formulated several mechanistic frameworks that quantitatively describe the basic processes and are able to deduce the impact on resolution (Figure 1), we are in the midst of developing theoretical means of knowing a priori which material properties mediate these intrinsic mechanisms. Addressing the experimental and theoretical challenges of elucidating these mechanisms, we aim to develop and apply a predictive model guiding the improvement of scintillator performance.
