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.
