The ETH Zurich AMS facilities: Performance parameters and reference materials

The current performance of all three AMS systems in operation at ETH Zurich, the 6 MV HVEC EN-Tandem facility “TANDEM”, the 0.5 MV NEC Pelletron “TANDY”, and the 0.2 MV system “MICADAS” is summarized. Radionuclides routinely measured with these AMS systems include 10Be, 14C, 26Al, 36Cl, 41Ca, 129I and the actinides. The reference materials used for the normalization of the AMS measurements at the ETH Zurich AMS facilities are presented. This paper therefore is a comprehensive status report of all three AMS systems currently operated by the Laboratory of Ion Beam Physics (LIP) at ETH Zurich and documents their performance and operation parameters.
