Energy Resolution and Rise Time of HPGe Detectors in High Magnetic Fields
نویسندگان
چکیده
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 degradation of the energy resolution by 1–2 keV was found, and a change in the rise time of the pulses by 50–200 ns was observed.

Performance 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 کاملUltraviolet detectors based on annealed zinc oxide thin films: epitaxial growth and physical characterizations
In this report, ultraviolet (UV) detectors were fabricated based on zinc oxide thin films. The epitaxial growth of zinc oxide thin films was carried out on bare glass substrate with preferred orientation to (002) plane of wurtzite structure through radio frequency sputtering technique. The structural properties indicated a dominant peak at 2θ=34.28º which was matched with JCPDS reference card N...
