We report here on the radiocarbon performance on the AARAMS HVE 1MV Tandetron. 14C analysis is carried out in charge state 2+. We have avoided Li interference by appropriate settings of the high-energy electrostatic analyzer and the 30° second high-energy magnet. The 14C machine background is determined using unprocessed graphite, which yielded 58,650±2032 14C yr determined as the average and standard deviation of four measurements. International standards, which are used to monitor the long-term performance of the 14C measurements, agree with the reported consensus values.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
