This paper describes the optimization of the geometric parameters of a Marinelli beaker to maximize the detection efficiency of sample measurement with a High Purity Germanium (HPGe) detector. A Monte Carlo model was developed and the detector pulse spectrum was studied for different beaker geometri
Using the peak efficiencies calculated by the PEAK code for 8 and 18% Ge(Li) detectors, the optimum geometry of large Marinehi-type vessels (5-60 L), under which the peak efficiency has its maximum value, was obtained in the energy region from 365 to 1332 keV. The result showed that the optimum geom
