Description
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.
