Abstract
Gamma-ray tracking in a closed array of highly segmented HPGe detectors
is a new concept for the detection of
-radiation.
Each of the interacting
-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
-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
-ray spectrometer. One implementation of this concept,
called GRETA (Gamma-Ray Energy Tracking Array), is
currently being under development at LBNL.
