Abstract

GRETA, the Gamma-Ray Energy Tracking Array, is an array of highly-segmented HPGe detectors designed to track γ-rays emitted in beam-physics experiments. Its high detection efficiency and state-of-the-art position resolution make it well-suited for Compton imaging applications. In this paper, we use simulated imaging data to illustrate how GRETA can be used to locate the emission points of photons produced during beam experiments. This lays the groundwork for nuclear lifetime measurements using Compton imaging.
