Description

Full text: In our AMS facility (NIES-TERRA), the NEC 5MV tandem Pelletron AMS (15SDH-2) have been used for various environmental studies since 1996. For past 10 years, we have made improvements such as installation of a type of MC-SNICS II ionizer, reconstruction of beam lines and exchanges of related electric instruments . With this renovation, we have developed method for ultramicroscale radiocarbon analysis with development of new graphitization systems and their improved protocol. In this conference, we report validations of ultra-microscale radiocarbon measurements to 1 μgC in improved AMS system and newly developed preparation methods.
