TI - ³⁹Ar Enrichment System Based on a 2.45 GHz ECR Ion Source J2 - Proc. of ECRIS2020, East Lansing, MI, USA, 28-30 September 2020 CY - East Lansing, MI, USA T2 - International Workshop on ECR Ion Sources T3 - 24 LA - english AB - Aimed at improving the ATTA’s (Atom Trap Trace Analysis) dating efficiency with ³⁹Ar radioactive isotope, an isotope enrichment system has been developed at IMP (Institute of Modern Physics) to increase the abundance of ³⁹Ar in the incident sample gas. In this enrichment system, a 2.45 GHz ECR ion source was designed to ionize sample gas and produce isotopes beams with several mA, and the isotopes beam is transported and separated in the separation beam line, which is consisted of two quadrupoles and an analysis magnet. The separated isotopes are collected by a rotated aluminum foil target. According to the recent cross-checked results with ATTA, high enrichment factor of ³⁹Ar isotope has been successfully reached. This paper will give a general introduction to the platform setup. The isotope enrichment efficiency is the critical issue for such a platform and will be specially discussed.
