摘要

A new AMS system (HVEE 4103Bo-AMS) was installed at Tono Geoscience Center, Japan Atomic Energy Agency in November 2019 and AMS experiments started in 2020. The system consists of a SO-110C Cs sputtering ion source, a low-energy spectrometer with an ESA and an injection magnet, a 300 kV tandem accelerator, a high energy spectrometer with two analyzing magnets and an ESA, and a gas ionization chamber for rare isotope measurement. The system is designed for high-sensitivity detection of 10Be, 14C, 26Al and 129I. A comparison with our 5 MV Pelletron is also given in this paper.
