Parameter optimization of a planar BEGe detector using Monte Carlo simulations

Determination of mass attenuation coefficient by numerical absorption calibration with Monte-Carlo simulations at 59.54 keV

“…For example, the existence of screws which hold the germanium crystal or the tilt of the crystal in the aluminium cap are never taken into account in the characteristics sheet [13]. The impact of the detector's geometry is important especially on gamma photons at low energy [14]. For upper energies, the correction factor is close to 1.…”

Development of a stochastic detection efficiency calibration procedure for studying collimation effects on a broad energy germanium detector

“…Rodenas et al [12] emphasize how the dead layer thickness [13] plays a non-negligible role in accurate Monte Carlo simulations. Due to the impossibility of performing physical measurements of the extension of the dead layer, in Monte Carlo detector simulations this value is tuned from experimental measurements; an accurate description of such a sensitivity analysis is given by Luis et al [14]. Having described accurately the detector's internal structure and the experimental set-up, it is possible to obtain calculated detection efficiencies that generate measured activity values from net peak areas of gamma-ray spectra [11,12].…”

Determination of the detection efficiency of a planar HPGe detector with a non‐uniform frontal dead layer

“…Monte Carlo simulations of radiation transport have been successfully used in the past as an alternative method to determine the detection efficiency or the response function of HPGe detectors. [3][4][5][6] Usually, employing the nominal dimensions of the detector provided by the manufacturer in the simulated geometry yields detection efficiencies that are not compatible with the experimental observations. Researchers modify either the crystal dimensions or the dead layer thicknesses, or both, until simulation reaches an agreement with experiment.…”
