N2 - We report here on the radiocarbon performance on the AARAMS HVE 1MV Tandetron. C-14 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 degrees second high-energy magnet. The C-14 machine background is determined using unprocessed graphite, which yielded 58,650 +/- 2032 C-14 yr determined as the average and standard deviation of four measurements. International standards, which are used to monitor the long-term performance of the C-14 measurements, agree with the reported consensus values.
