Design, Construction and Performance Evaluation of a HPGe Detector Shield
A multilayer passive shield composed of low-activity lead (Pb), copper (Cu), tin (Sn) and iron (Fe) was designed and manufactured for a coaxial HPGe detector placed at a surface laboratory for reducing background radiation and radiation dose to the personnel. The performance of the shield was evaluated and efficiency curves of the detector were plotted by using of various standard sources in di...
متن کاملGamma-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 کاملPerformance of a Portable, Electromechanically-Cooled HPGe Detector for Site Characterization
High-resolution, germanium detectors (HPGe) have long been used for radionuclide characterization of nuclear sites, both buildings and large areas, for the purpose of cleaning up the site. Several systems consisting of a detector, mobile support, collimators and software for data collection and spectrum analysis have been made by national laboratories and commercial companies. The efficacy of t...
متن کاملApproximations for Performance of Energy Detector and p-Norm Detector
Although the approximations based on the central limit theorem (CLT) for the detection probability (Pd) of the energy detector and of its more generalized cousin, the p-norm detector, are accurate for large sample sizes, their accuracy is poor otherwise. A recent work has addressed this problem by developing a cube-of-Gaussian approximation (CGA). However, CGA may not be the only option and thu...
