Abstract: A primary tool for detecting undeclared nuclear activities is the analysis of uranium-bearing particles collected on cotton swipes. For many years SIMS has been used as one of the mainstay techniques for particle analysis of Nuclear Safeguards samples. SIMS is unique in that it is the only technique that can both localize the particles of interest and also provide the isotopic composition of single particles. This paper presents data obtained on standard uranium particle samples using Large Geometry (LG) – SIMS instruments [1] equipped with the newly developed, Automated Particle Measurement (APM) screening software [2]. Both sample screening measurements and micro beam analyses on individual particles are presented. The enhanced performance of the SIMS method for Nuclear Safeguards applications using LG-SIMS instruments equipped with automated screening capabilities is also discussed. Keywords: SIMS; LG-SIMS; uranium; particles; nuclear safeguards; nuclear forensics, CAMECA, ion microprobe, IMS 1280.
