High-purity germanium (HPGe) single crystals find their applications as radiation detectors especially for spectroscopy of high-energy photons and particles in nuclear physics. Growing “detector-grade” HPGe crystals, with tailored structural defects controlled impurity content, uniform throughout the crystal is a challenging task this type crystalline semiconductor material. All different proce...

The potential of GENIUS as a dark matter detector is discussed. A study was performed to demonstrate the good behaviour of the proposed detector design of naked HPGe-crystals in liquid nitrogen. The expected background components were simulated and are discussed in some detail.With the obtained background GENIUS could cover a large part of the favoured MSSM parameter-space.

High-purity germanium (HPGe) is a vibration-sensitive, high-resolution detector. It has been found that microphonic noise induced by vibration and electromagnetic interference from EMC causes energy resolution degradation in HPGe detectors. In this paper, to enhance the of pulse tube-cooled high purity detector, passive isolation system for portable tube cooler (PTC) was employed investigated. ...

To obtain high quality of results in gamma spectrometry, it is necessary to select the best HPGe detector for particular measurements, to calibrate energy and efficiency of gamma detector as accurate as possible. To achieve this aim, the convenient detector model and gamma source can be very useful. The purpose of this study was to evaluate the soil specific activity using two HPGe model (BEGe-...

Gamma spectroscopy is an analytic technique that identifies isotopes through gamma rays. Currently, widely used in several science fields, for instance, the study of hydrodynamics soils and other applications. Considering development computers, it has been developed Monte-Carlo simulation packages, order to estimate response detectors. This work aims develop a GEANT4 application full energy pea...
