Abstract

Abstract We report here on the radiocarbon performance on the AARAMS HVE 1MV Tandetron. 14 C 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 14 C machine background is determined using unprocessed graphite, which yielded 58,650±2032 14 C yr determined as the average and standard deviation of four measurements. International standards, which are used to monitor the long-term performance of the 14 C measurements, agree with the reported consensus values.
