Surface 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 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 کاملSurface characterisation of Germanium detectors
Germanium-detectors are the most sensitive high-resolution γ detectors available and are the instrument in nuclear structure physics which allows important information about the structure of atomic nuclei to be obtained. The technology of High purity Germanium detectors is presented in [1]. The reported work is motivated by the needs for a new mechanical treatment procedure within the manufactu...
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 کاملFast analytical methods for the correction of signal random time-shifts and application to segmented HPGe detectors
Detection systems rely more and more on on-line or off-line comparison of detected signals with basis signals in order to determine the characteristics of the impinging particles. Unfortunately, these comparisons are very sensitive to the random time shifts that may alter the signal delivered by the detectors. We present two fast algebraic methods to determine the value of the time shift and to...
