Study of Zone Importance for Gamma-Rays in Germanium Detectors by Monte Carlo Simulation

Abstract:
A computer simulation code based on the Monte Carlo method has been developed to study the response of a cylindrical germanium detector to incident gamma rays of various energies as a function of depth along the detector axis. The code first generates a reference spectrum for the whole volume of the detector. The detector is then sliced into a series of cylindrical cells. The contribution of each individual cell is evaluated by comparing the reference spectrum with the spectrum generated from the detector`s response function that excludes the contribution of the cell being considered. When the difference between these two spectra is plotted as a function of depth along the detector axis, a curve is obtained that shows how the importance of a given cell varies as a function of its position in the detector volume. Such a curve has a maximum that is deeper inside the detector volume and is more pronounced for higher energies. Moreover, the results of this study indicate that the relative importance of the response function of each cell is determined by the full energy peak, while the compton continuum has little effect on it.
