For the sake of enhancement of CTBT verification regime

Fukui, Yasuhito 

This presentation shows how the CTBT verification regime can be enhanced. In these 20 years, technological innovation has progressed and in addition to the commissioned IMS, the monitoring stations were also constructed for the scientific purpose. For example, infrasound and seismic wave monitoring stations are constructed separately beside IMS stations. Furthermore, these non-IMS seismic data is available via internet and using these data more precise determination of epicenter can be possible. As for radionuclide monitoring, other noble gas observation is performed in addition to IMS. In cooperation with CTBTO preparatory commission and JAEA, noble gas back ground measurement is conducted jointly in Mutsu and Horonobe in Japan with TXL equipment. Thus, using all these data, in order to enhance precision of verification regime, we seek the possibility of a close cooperation among the research institutes concerned.
