GERMANIUM DETECTOR EFFICIENCY FOR A MARINELLI BEAKER SOURCE-GEOMETRY USING THE MONTE CARLO METHOD

The full energy peak efficiency values of an HPGe detector covering an energy range of 81-1836 keV were determined for a Marinelli beaker photon source-geometry. Detector efficiency for energy depositions from source volumes of 300 and 400 ml were simulated using the Monte Carlo method. Experimental...

Summary:The full energy peak efficiency values of an HPGe detector covering an energy range of 81-1836 keV were determined for a Marinelli beaker photon source-geometry. Detector efficiency for energy depositions from source volumes of 300 and 400 ml were simulated using the Monte Carlo method. Experimental data points from measurements of standard sources were used in validating the method while least-squares functions were used to obtain fitted values from the experimental data sets. The efficiency values from the Monte Carlo simulation, experimental results, and fitted functions were found to be in agreement with deviations of less than 10% for most data points.
