 note = {A second ^<14>C-AMS system (Model 4130-AMS), built by High Voltage Engineering Europe (HVEE), B.V., The Netherlands, was delivered to Nagoya University in 1996/97. Acceptance tests were completed in January of 1999, and routine measurements began in mid-2000. Since completion of the acceptance tests in early 1999, we have encountered a lot of trouble with the machine, in particular in 2002. We have replaced a RF-transformer for high voltage generation system, a GVM motor to measure high voltage applied to the terminal of the tandem accelerator, etc, in 2002. After these troubles, the machine is relatively working well, expect for minor problems. However, it should be stressed that even a minor malfunction, ^<14>C measurements are not possible with the system. The numbers of targets measured were 330, 1430, 2077, 1003, 1979 and 1679 in the years 1999, 2000, 2001, 2002, 2003, 2004, respectively. In 2005, we have measured totally 1771 targets during the machine operations of 39 weeks. Thus the total number of targets measured was over 10,000 at the end of November in 2005. In 2005, we have finally opened the accelerator tank again after three years and a half from the severe machine trouble in 2002. The problem this time was a disorder of power transport system to the terminal pump (turbo molecular pump) that is equipped on the high voltage terminal of the accelerator tank to circulate argon gas efficiently for electron stripping from negative carbon ions. The repair of the damaged system was done in two weeks. In spite of other minor but many problems, we can now continue ^<14>C measurements with our AMS system., 第18回名古屋大学年代測定総合研究センターシンポジウム平成17(2005)年度報告 Proceedings of the 18th symposiumon on Chronological Studies at the Nagoya University Center for Chronological Research\
