- Abstract
Very sensitive methods, presently mainly accelerator mass spectrometry (AMS) are necessary for analysis of cosmogenic
10Be in the environment. AMS is mainly limited by the stable isobar
10B, while the requirements for mass separation are the least stringent of all standard isotopes analyzed by AMS. We tested a possibility to measure
10Be using a small switching magnet as an analyzer of accelerated ions, and an ionization chamber with a silicon nitride foil stack used as a passive absorber. A detection limit of 10
-12 for the
10Be/
9Be isotopic ratio was obtained using this technique, which was mainly determined by scattering of
9Be
+2 ions on residual gas inside the switching magnet.
