P-Type High Purity Germanium Ring Diode Detectors for use in Neutrinoless Double Beta Decay Experiments

P-Type Enriched High Purity Germanium (HPGe) detectors are useful in rare event searches because of their excellent energy resolution. To measure rare single-site events, such as neutrinoless double beta decay, it is critical to reject multisite events while keeping the single-site events to minimize background signal in measurements. The Ring-Diode Detector (RDD) is a proposed HPGe detector geometry designed to have excellent single-site versus multi-site event discrimination abilities. The RDD electric and potential fields were simulated and the depletion voltages of various detector configurations and impurity profiles were estimated in Julia using the Solid State Detectors Packages. The effects of the electric field on charge clouds deposited within the fully biased RDD were discussed. Further analysis of the RDD's event discrimination properties, including analysis of the simulated pulse-shapes, is suggested to better ascertain its event discrimination capabilities.
