Micadas: A versatile radiocarbon dating system in routine operation — •Lukas Wacker¹, Irena Hajdas¹, Bernd Kromer², Mojmir Nemec³, Matthias Ruff³, and Hans-Arno Synal¹ — ¹Ion Beam Physics, ETH Zurich, Switzerland — ²Heidelberg Academy of Sciences, Germany — ³Department of Chemistry and Biochemistry, University of Bern, Switzerland

The mini carbon dating system (Micadas) at ETH Zürich was built 4 years ago. While it was mainly used for experimental development the first 3 years, we will now present our first experiences in routine operation for gaseous and solid radiocarbon samples.

We will show the prospects of the direct measurement of carbon dioxide with the gas ion source for either small samples or samples where low precision is required. Beyond that, we will demonstrate the excelled stability and reproducibility of the Micadas system on high-precision measurements of solid samples. This will end in a discussion about the perspectives of our mini radiocarbon dating system.
