A novel HPGe detector for gamma-ray tracking and imaging

A novel, large-volume High Purity Germanium (HPGe) detector that will provide gamma-ray detection with both sub-mm position resolution and high efficiency is under development. This design is based on a coaxial HPGe geometry and employs a point contact along with segmentation of the outer electrode. Calculations indicate that this device will be capable of achieving values of position sensitivity which are approximately a factor of four or five greater than conventional gamma-ray tracking detectors.
