Abstract

Ion source is the key part of an Accelerator Mass Spectrometry (AMS) in view of analytical sensitivity, stability and accuracy. SO-110 Cs⁺ sputtering ion source developed by High Voltage Engineering Europe, is dedicated to AMS for both solid and gas target sources, which has been successfully applied to AMS instruments including one installed in Xi'an AMS center. By investigation of the effect of various parameters, such as the target preparation, holder characteristics, matrix selection and the ratio between AgI and matrix on AMS measurement of ¹²⁹I using SO-110 ion source, Cu is the suitable holder material, and Nb powder is the best matrix, and the optimal ratio of AgI:Nb is 1:3. A machine background of 1.52×10^-14 for ¹²⁹I/¹²⁷I was obtained using a NaI sample directly mixed with Nb powder and pressed in Cu target holder.
