A new type of radiation detector, a p-type modified electrode germanium diode, is presented. It is shown that the prototype displays, for the first time, a combination of features (mass, energy threshold and background expectation) required for a measurement of coherent neutrino–nucleus scattering in a nuclear reactor experiment. First results are presented from its calibration using sub-kiloel...

Measurement of radon in water by g-ray spectrometry using a HPGe detector has been investigated to determine aquifer characteristics. The radon activity concentration is determined by taking the weighted average of the concentrations derived from g-ray lines associated with Pb and Bi decay. The role of accurate radon data to representatively sample aquifers was also investigated by studying a s...

Coherent and incoherent scattering cross section measurements have been carried out using a HPGe detector on elements in the range of Z = 13 50 using Am gamma rays. The cross sections have been derived by comparing the net count rate obtained from the Compton peak of aluminium with the corresponding peak of the target. The measured cross sections for the coherent and incoherent processes are co...

A new method of the perturbed angular gamma-gamma-correlation (PAC) measurements was developed using one HPGe detector only (1-PAC). For quantifying the perturbation factor, the ratio R gamma 1 + gamma 2 of the summing peak composed of two cascade gamma-rays (the perturbation-affected parameter) to the summing peak composed of one gamma-ray and one X-ray (the perturbation non-affected parameter...

Measurement of 238U, 233Th and 40K concentrations in soil samples collected from Ziggurat Dur-Kurigalzu west region Baghdad, have been evaluated, using high purity germanium detector. The activity varied 16.040 to 26.620 , 14.510 31.480 153.820 266.320 with average values 20.604±2.9 24.534±3.3 212.22±25.1 respectively. importance these measurements lies the estimation radiation risk, radium equ...

The capabilities of future Germanium (HPGe) detector arrays consisting of large volume segmented crystals like AGATA [1] will depend heavily on the performance of γray tracking. The most crucial component in the whole concept is the pulse shape analysis (PSA). The efficiency of tracking algorithms hinges on the ability of the PSA to reconstruct the interaction locations accurately, especially f...

Within the present work HPGe detectors of Institute Nuclear and Particle Physics at NCSR “Demokritos” were fully characterized in terms their efficiency. The three n-type 80% relative efficiency recently acquired framework CALIBRA project. All are equipped with carbon epoxy windows that allow detection low energy γ-rays. Beside characterization, modeled by means GEANT4. In all cases simulated d...
