Gamma-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 کاملA Comparative Study of Field Gamma-ray Spectrometry by NaI(Tl) and HPGe Detectors in the South Caspian Region
Natural radionuclides present in soil as well as certain anthropogenic radionuclides released to the environment are the major contributors to terrestrial outdoor exposures. In the assessment of human exposures from environmental radioactivity, besides the conventional method of soil and vegetation sampling combined with laboratory based analyses of environmental media, the other choice would b...

متن کاملDetermination of Primordial Radionuclides in Natural Samples Using HPGe Gamma-Ray Spectrometry
Distributions of primordial radionuclides in soil and vegetables were investigated using high-purity germanium gamma-ray spectrometry. Gamma-ray spectrometry is one of the most accepted and widely used techniques for the detection and analysis of radioactive materials for a wide range of activity. Important properties of the employed gamma-ray detector were also determined to ensure the accurac...
متن کاملPixelized Gas Micro-well Detectors for Advanced Gamma-ray Telescopes
We describe possible applications of pixelized micro-well detectors (PMWDs) as three-dimensional charged particle trackers in advanced gamma-ray telescope concepts. A micro-well detector consists of an array of individual micro-patterned gas proportional counters opposite a planar drift electrode. When combined with pixelized thin film transistor (TFT) array readouts, large gas volumes may be i...
