IAEA Consultant Meeting, Wien 1-2 March 2010

6. Two beamlines for AMS: A) for 14 C dating: 2 off-center Faraday cups for parallel current measurement of 12 C 3+ and 13 C 3+, while the 14 C 3+ detection is by means of an electrostatic analyzer and a gas proportional counter. B) Heavy ion ("AUSTRALIS") beamline with HICONEX Cs microbeam (30-300 mm) multielement ("AUSTRALIS") negative ion source. The magnet is able of analyzing 6+ (or higher charge state) ions of all elements up to U at 2.5 MV terminal voltage. Sequential analysis of different isotopes (around +-3% of center mass) in the magnet is possible by means of the "fast bouncing" technique.
