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.
