Performance of the compact HVE 1 MV multi-element AMS system

HVE has tested the performance of its first compact 1 MV AMS system. The system is primarily designed for the measurement of 14C, 10Be and 26Al, but additionally supports the measurement of heavy ions like iodine and plutonium. The tests confirmed the flexibility of a system that results from its 1 MV nominal terminal voltage, as it allows the use of various charge states for the analysis of e.g. 14C, supports 10Be analysis with good detection efficiency and permits the analysis of heavy ions like 129I and Pu. For the analysis of 10Be, the isobaric 10B is removed by means of the nuclear charge dependent energy loss in an absorber foil in front of the electrostatic analyser. The results of the performance tests for 14C-, 10Be- and 26Al-analyses are presented in this paper.
