AMS at low energies - Recent developments and applications in environmental sciences — •Marcus Christl, Arnold Müller, Lukas Wacker, Vasily Alfimov, Martin Stocker, Hans-Arno Synal, and Martin Suter — PSI/ETH Laboratory of Ion Beam Physics, Institute for Particle Physics, ETH-Zürich, Switzerland

Considerable progress has been made over the past decade in establishing long-lived radionuclide measurements on small, low energy AMS systems. Small AMS machines are cost saving alternatives for laboratories in the earth and environmental sciences and in many cases these systems now may compete with much larger machines with respect to over all efficiency, precision, and accuracy. This talk gives an overview about the most recent technical developments and demonstrates the potential of compact AMS machines for their application in the earth’s and environmental sciences. Various examples will be presented covering a wide range of applications (e. g. earth’s sciences, environmental monitoring, dating) as well as a wide mass range (Be-10, C-14, Al-26, I-129, Pu-, Pa-, and U-isotopes).
