Abstract :
During the past few years the construction of Tsukuba AMS system at the University of Tsukuba has been made. A “molecular pilot beam” method is used for AMS measurements without any modification to the existing tandem system. The efficiency and the reproducibility of 14C measurement have been improved and the results of dating of groundwater and a dating of fossil foraminifer are preliminary reported. The measurement of an absolute 36Cl35Cl ratio is tried with tri-molecular pilot beam.
