Webnamely Gamma Spectrometry System. The accuracy of the measurement very much depends on the performance of the various system detectors and one of those well-known and popular types of detector is the High-Purity Germanium (HPGe) detector. In order to achieve high quality outcome, the performance of the HPGe detector shall be verified … WebFeb 23, 2024 · High-Precision Spectroscopy with PGT HPGe. Posted on February 23, 2024 by maxfomitchev. High purity germanium detectors are the highest resolution gamma detectors available. The only disadvantage is the need for cryogenic cooling, which is traditionally accomplished using a liquid nitrogen Dewar or more recently using a …
WebThe high resolution detectors (HPGe) are suitable for samples containing many radionuclides (e.g. from the natural radioactive series), when the gamma-ray spectrum presents a large number of peaks to be deconvoluted. These detectors are expensive and must be kept at very low temperatures (in liquid nitrogen) for a correct functioning. WebIn the book, a new gamma spectroscopic method, gravitational gamma spectrometry, is developed. It has a resolution hundred million times higher than the usual Mössbauer spectrometer. Another important topic of this book is resonant scattering of annihilation quanta by nuclei ... The validation of these models requires high-resolution, multi ...
