Energy Resolution and Rise Time of HPGe Detectors in High Magnetic Fields
Future experiments on hypernuclear high-resolution γ-spectroscopy with high-purity germanium detectors with the FINUDA apparatus at the DAΦNE accelerator and with the PANDA apparatus at the FAIR facility require the operation of these detectors in high magnetic fields (B ≈ 1T). VEGA and Euroball cluster HPGe detectors were tested in the field provided by the ALADiN magnet at GSI. A small degrad...
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 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 کاملEvaluation of New Digital Detectors for High Resolution Radiography
Abstract: In the actual study, two digital detectors were investigated : an amorphous silicon flat panel and a TDI multilinear detector. The contrast and IQI sensitivity was selected to compare flat panel and film radiography. The influence of X-ray conditions was assessed in the case of flat panel. Spatial resolution of both digital detectors was assessed by adapting the geometrical magnificat...
متن کاملNew Developments in Hybrid Photon Detectors
New developments in HPD design are presented, triggered by applications in high energy physics and astrophysics. The presented HPD designs are based on three innovations. (i) In order to achieve the highest possible surface coverage in a RICH detector, we introduced a photoelectron focussing method which is efficient to the periphery of the photocathode. (ii) To prevent positive ion feedback in...
