Abstract
Gamma-ray tracking in a closed array of highly segmented HPGe detectors is a new concept for the detection of $\gamma$-radiation. Each of the interacting $\gamma$-rays is identified and separated by measuring the energies and positions of individual interactions and by applying tracking algorithms to reconstruct the scattering sequences, even if many $\gamma$-rays hit the array at the same time. The three-dimensional position and the energy of interactions are determined by using two-dimensionally segmented Ge detectors along with pulse-shape analysis of the signals. Such a detector will have new and much improved capabilities compared to current $\gamma$-ray spectrometer. One implementation of this concept, called GRETA (Gamma-Ray Energy Tracking Array), is currently being under development at LBNL.
