“…An indication of potential heterogeneity of the U isotopic composition of the CMX-4 UO 2 pellets was gained through secondary ion mass spectrometry (SIMS) analysis collecting particle from the pellets by swiping the surfaces [ 22 ]. Implementing an automated particle measurement (APM) software, preliminary SIMS analysis confirmed the frequency distribution of the 235 U enrichments of the two CMX-4 UO 2 pellets established with LA-MC-ICP-MS in this study ( Fig.…”

“…The variety of diverse U isotopic compositions of solid nuclear materials can be also assessed with secondary ion mass spectrometry (SIMS). This was demonstrated during the fourth Collaborative Materials Exercise (CMX-4) where U particles were collected from a pellet surface on a cotton swipe by wiping the solid sample [ 22 ]. These particles were subsequently analysed individually by SIMS.…”

“…Within this special section, the reader will find major outcomes from CMX-4 contained within one of seven technical articles organized by technical area [10][11][12][13][14][15][16], and one additional article briefly describing the experiences of seven of the laboratories participating in the CMX series of exercises for the first time [17]. The latter chronicles the challenges these newcomers faced, from the receipt and handling of special nuclear materials, to the timely analysis and reporting of results under operational timelines-all made possible by transforming often ''general use'' radioanalytical laboratories to execute analytical plans and quality assurance/quality control processes of a sufficient rigor for a court of law.…”

“…For the first time during a CMX, secondary ion mass spectrometry (SIMS) was employed by three separate laboratories to measure isotopic inventories of U on individual particles. Their efforts are summarized in Stebelkov et al [16]. Results from these advanced analyses provided the most definitive evidence for correctly identifying or refuting connections between ESs and highlighted an important and emerging technology in nuclear forensic science.…”
