Simulation and Real-Time Analysis of Pulse Shapes from HPGe Detectors
The capabilities of future Germanium (HPGe) detector arrays consisting of large volume segmented crystals like AGATA [1] will depend heavily on the performance of γray tracking. The most crucial component in the whole concept is the pulse shape analysis (PSA). The efficiency of tracking algorithms hinges on the ability of the PSA to reconstruct the interaction locations accurately, especially f...
متن کاملMatrix formalism and singular value decomposition for the location of gamma interactions in segmented HPGe detectors
Modern coaxial and planar HPGe detectors allow a precise determination of the energies and trajectories of the impinging gamma-rays. This entails the location of the gamma interactions inside the crystal from the shape of the delivered signals. This paper reviews the state of the art of the analysis of the HPGe response function and proposes methods that lead to optimum signal decomposition. Th...
متن کاملGamma-ray imaging with coaxial HPGe detector
We report on the first experimental demonstration of Compton imaging of gamma rays with a single coaxial high-purity germanium (HPGe) detector. This imaging capability is realized by two-dimensional segmentation of the outside contact in combination with digital pulse-shape analysis, which enables to image gamma rays in 4p without employing a collimator. We are able to demonstrate the ability t...
متن کاملSurface projection of HPGe- detectors
Several encapsulated single Germanium detectors have been mounted in one unit and integrated in a cryostat, in order to build efficient spectrometers to detect γ radiation emitted by nuclei excited in nuclear reactions. This kind of crystal encapsulation offer advantages compared to standard set-up of HPGedetectors. The basic aim of the following work is to develop a new capsule technology, in ...
متن کاملPulse shape analysis in segmented detectors as a technique for background reduction in Ge double-beta decay experiments
The need to understand and reject backgrounds in Ge-diode detector double-beta decay experiments has given rise to the development of pulse shape analysis in such detectors to discern single-site energy deposits from multiple-site deposits. Here, we extend this analysis to segmented Ge detectors to study the effectiveness of combining segmentation with pulse shape analysis to identify the multi...
