Abstract

The measurement capabilities of the new accelerator mass spectrometry (AMS) system at the 10 MV FN tandem accelerator of CologneAMS has been extended with AMS measurements of Fe-60/Fe in the range of 10(-8),10(-10) and 10(-12). The measurements were conducted combining a 135 degrees gas-filled magnet and a subsequent energy loss measurement in a 5 anode gas ionization chamber. This technique allows a good separation of the stable isobar 60 Ni resulting in a suppression by a factor of 10(7) for the high energy mass spectrometer. With this a limit for the background level of 7.10(-14) was achieved. The calculation of the error normalized sensitivity allowed a first comparison to other AMS laboratories.
