内容記述
A model 4130-AMS 14C analyzer, produced by General Ionex Corporation, USA, was successfully introduced to the Radioisotope Center, Nagoya University, in 1981/82. The first 14C signal was detected with the machine in February 1983 and routine 14C measurements were started in the autumn of 1983. The AMS system has processed totally 8,652 unknown samples by July in 2000, after that time, he transferred his role of 14C measurements to another new successor. A second AMS system, dedicated to high-precision and high-accuracy 14C measurement, with a recombinator system to measure three carbon isotopes 12C, 13C and 14C simultaneously, produced by High Voltage Engineering Europe BV, The Netherlands, was installed in 1996/97. 14C measurements with the machine were started in 1999 and the machine has measured totally 23,921 graphite targets by the end of December 2015. Following the results of applications of the two AMS system for 14C measurements at Nagoya University, a brief history of the developments of AMS techniques and applications mainly in Japan is described. In addition,future perspectives of AMS are discussed.
