| 内容記述 | n AMS system (Model 4130-AMS) dedicated to^<14>C measurements, built by High Voltage Engineering (HVE), B.V., The Netherlands, was delivered to Nagoya University in 1996/97. Acceptance tests of its performance on carbon isotope measurements 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 troubles with the machine, particularly in 2002. Since the end of 2002, the machine has relatively worked well, expect for minor problems. The standard deviation (one sigma) of the ^<14>C/^<12>C ratio is around ±0.3% to ±0.4% (a bit larger than the uncertainty of about ±0.3% calculated from ^<14>C counting statistics) and that of the corresponding ^<13>C/^<12>C ratio is ±0.03% to ±0.07%, as are tested for HOxII targets. The number of targets measured was 330, 1430, 2077, 1003, 1,979, 1679, 1771 , 1,115, 1,339, and 866 in each year from 1999 to 2008, respectively, and total number of target measured is 13,590. Since November 1^st, 2007, we had a scheduled shutdown of the AMS system, owing to the improvements of the building, Furukawa Memorial Hall, against earthquake invasion expected in near future around Tokai area, central Japan. In June of 2008, we started 14C measurements again, encountering also several troubles as we had experienced before. A full overhaul of the AMS system was conducted by a HVE engineer in October of 2008. During the special maintenance, a high-voltage generator, two accelerator tubes and an ion source system were completely tested. 150 diodes of the high-voltage generator, 27 registers for dividing high voltage at the accelerator tubes, and two sets of insulators in the ion source were exchanged with new ones. Thus more than half of 2008 was spent for the improvement of the building and maintenance of the AMS system, and totally 866 targets were analyzed. | |||||
