    Abstract

    Experimental efficiency calibration of high purity germanium (HPGe) detectors is often expensive and time consuming. That is why many methods, such as Monte Carlo simulations and analytical methods have been proposed and examined. One of those methods is virtual point detector (VPD) method, the approximation of whole bulk detector with a point detector, located at the effective interaction depth. Also, one of efficiency transfer programs is EFFTRAN, the software that calculates efficiency and coincidence summing. The aim of this paper is to use EFFTRAN software for obtaining effective interaction depth of the detector, needed for virtual point detector method calculations. Since the effective interaction depth represents the geometry of the detector, the discrepancy between the calculation and measurement can be used to estimate uncertainty, originating from the defining of detector geometry when EFFTRAN is used. For the purpose of estimation of uncertainty, semiempirical formula based on VPD, will be utilized.
