- Abstract
Our AMS system, with the gas-filled detector system GAMS, has been optimized for measurements with Mn-53. A high sensitivity has been achieved. A newly installed cesium sputter ion source yields an improved emittance, and thus a higher mass resolution. By the extraction of the manganese molecule MnF- instead of MnO- we can suppress the isobaric chromium background in the ion source by more than a factor of three. The GAMS system achieves an isobaric suppression factor of about 3 x 10(8). Measurements on blank samples yielded upper limits for the Mn-53/Mn-55 ratios of 7 x 10(-15).
