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

摘要

HVE has tested the performance of its first compact 1 MV AMS system. The system is primarily designed for the measurement of ~(14)C, ~(10)Be and ~(26)Al, 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. ~(14)C, supports ~(10)Be analysis with good detection efficiency and permits the analysis of heavy ions like ~(129)I and Pu. For the analysis of ~(10)Be, the isobaric ~(10)B 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 ~(14)C-, ~(10)Be- and ~(26)Al-analyses are presented in this paper.
