文摘

The characterization and ray-tracing algorithm in ISOCS/LabSOCS has been extended to calculate full energy peak and total efficiencies for the Small Anode Germanium Well detector. The extension allows for true coincidence summing correction using the standard algorithm in the Genie 2000 software. The accuracy of the full energy peak efficiency calculation and the coincidence summing correction has been experimentally validated to be the same as for non-well detectors.
