The results of engineering an intelligent preamplifier for high purity germanium gamma-detectors are presented. An is a low-noise, speed resistive feedback charge-sensitive with built-in microcontroller and additional units that enable control detector parameters. It also allows the performance managing internal testing pulser, sensor liquid nitrogen level in Dewar, humidity, pressure temperatu...

Abstract The time analysis of the signal induced by drift charge carriers in high purity germanium detectors provides information on event topology. Millions are produced a typical event. Their initial distribution, stochastic diffusion and Coulomb self-repulsion affect structure signal. We present comprehensive study these effects evaluate their impact discrimination capabilities for three geo...

Abstract In this study, the effect of various types fertilizers on natural radioactivity levels in agricultural soil was investigated research. The activity concentration 226Ra, 232Th, and 40K fertilizer samples were determined by using gamma-ray spectroscopy a high-purity germanium (HPGe) detector to determine concentrations 40K. for phosphate raw (2300-5400) Bq/kg, (9-53) (56-3000) respective...

The DEcay SPECtroscopy (DESPEC) setup for nuclear structure investigations was developed and commissioned at GSI, Germany in preparation a full campaign of experiments the FRS Super-FRS. In this paper, we report on first employment hybrid configuration with AIDA implanter coupled to FATIMA LaBr3(Ce) fast-timing array, high-purity germanium detectors. Initial results are shown from carried out s...

The system using X-gamma coincidence technique for the standardizing radionuclide, which present simple and complex decay scheme with X-rays of energy below 100 keV has deployed by Radionuclide Laboratory (LNMRI), Brazil. work was carried a sodium iodide detector, gamma photons, in combination high purity germanium detector X-rays. Samples 65Zn 133Ba were standardized results both radionuclides...
