Abstract
Traditional ways of determining the absolute fullenergy peak efficiencies of highpurity germanium HPGe detectors are often time consuming cost prohibitive or not feasible A software package KMESS Kevin’s Mesh Efficiency Simulator Software was developed to assist in predicting these efficiencies It uses a semiempirical meshgrid method and works for arbitrary source shapes and counting geometries The model assumes that any gammaray source shape can be treated as a large enough collection of point sources The code is readily adaptable has a webbased graphical frontend and could easily be coupled to a 3D scanner As will be shown this software can estimate absolute fullenergy peak efficiencies with good accuracy in reasonable computation times It has applications to the field of gammaray spectroscopy because it is a quick and accurate way to assist in performing quantitative analyses using HPGe detectorsThis manuscript has been authored by Los Alamos National Laboratory and The University of Texas at Austin This manuscript has also been authored by National Security Technologies LLC under Contract No DEAC5206NA25946 with the US Department of Energy The United States Government retains and the publisher by accepting the article for publication acknowledges that the United States Government retains a nonexclusive paidup irrevocable worldwide license to publish or reproduce the published form of this manuscript or allow others to do so for United States Government purposes
