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 کاملPerformance of HPGe Detectors in High Magnetic Fields
A new generation of high-resolution hypernuclear γ-spectroscopy experiments with high-purity germanium detectors (HPGe) are presently designed at the FINUDA spectrometer at DAΦNE, the Frascati φ-factory, and at PANDA , the pp hadron spectrometer at the future FAIR facility. Both, the FINUDA and PANDA spectrometers are built around the target region covering a large solid angle. To maximise the ...
متن کاملGeant4 hadronic physics status and validation for large HEP detectors
Optimal exploitation of hadronic final states played a key role in successes of all recent collider experiment in HEP, and the ability to use hadronic final states will continue to be one of the decisive issues during the analysis phase of the LHC experiments. Monte Carlo techniques facilitate the use of hadronic final states, and have been developed for many years. We will give a brief overvie...
متن کاملHPGe and Scintillation Detectors Comparisons on Waste Drums Radioactivity Measurement
Two measurement systems, one being comprised of three HPGe detectors and the other being a 4π measurement system of the assembly of 10 sets of scintillation detectors, were compared for their measurement performance in operations of radioactive waste drum radioactivity measurement and clearance and release operation of decommissioning. The system features of the former were high costs, capable ...
متن کاملOptical simulation of monolithic scintillator detectors using GATE/GEANT4.
Much research is being conducted on position-sensitive scintillation detectors for medical imaging, particularly for emission tomography. Monte Carlo simulations play an essential role in many of these research activities. As the scintillation process, the transport of scintillation photons through the crystal(s), and the conversion of these photons into electronic signals each have a major inf...
