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 Be-10, C-14, Al-26, Cl-36, Ca-41, I-129 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.
