Uranium Isotopic Analysis with the FRAM Isotopic Analysis Code

摘要

FRAM is the acronym for Fixed-energy Response-function Analysis with Multiple211u001eefficiency. This software was developed at Los Alamos National Laboratory 211u001eoriginally for plutonium isotopic analysis. Later, it was adapted for uranium 211u001eisotopic analysis in addition to plutonium. It is a code based on a self-211u001ecalibration using several gamma-ray peaks for determining the isotopic ratios. 211u001eThe versatile-parameter database structure governs all facets of the data 211u001eanalysis. User editing of the parameter sets allows great flexibility in handling 211u001edata with different isotopic distributions, interfering isotopes, and different 211u001eacquisition parameters such as energy calibration and detector type.
