シングルステージ加速器質量分析装置を用いた放射性炭素分析とその応用
The National Electrostatics Corporation (NEC) 250kV single-stage AMS (YS-AMS) was installed in March 2013 at the Laboratory of Accelerator Mass Spectrometry (LAMS), the Atmosphere and Ocean Research Institute, The University of Tokyo. This is the first single-stage AMS system installed in Japan. The system is equipped with a 40 solid sample ion source (MC-SNICS-II), sequential injection system at low energy mass spectrometry side, open air 250kV high energy deck including helium gas stripper which acts as a molecular dissociation, analyzing magnet, electrostatic analyzer, sequential post-accelerator deflector, and final detector. High throughput and high precision measurements have been achieved and its precision is reached typically at 0.1 percent level. In this presentation, we will introduce present status of the machine as well as several applications to understand environmental as well as biological studies.
