Acceptance tests on its performance on carbonisotope- ratio measurements were completed in January of 1999 and routine measurements began in mid-2000. The numbers of targets measured from 1999 to 2016 were: 330, 1430, 2077, 1003, 1,979, 1679, 1772, 1115, 1339, 866, 1300, 1701, 1449, 1634, 1351, 1741, 1156, and 466, respectively (24,387 were measured by the end of June 2016). We briefly describe the maintenance processes for the AMS system in 2016. The Tandetron AMS system at Nagoya University encountered several serious problems in 2016. First, the high voltage of the accelerator broke down frequently for no clear reasons. Any sparks happened before these voltage downs. Second, a compressor for the cryo-pumping system stopped suddenly. Parts for maintaining the pump system are no longer supplied by the manufacturer, leaving us no choice but to replace the cryo-pumping system with a turbomolecular pumping system. Third, ion source cleaning had to be conducted due to a shortage of Cs in the container. Fourth, the excessively high temperature of the circulating water used to cool down the power supply system for two high-energy mass-analyzing magnets forced us to replace the system with a magnet power supply system cooled by air. Fifth, a power supply unit for the servo-amplifier controlling the motor for target exchanging function was found to be out of order. Replacement with a spare unit corrected the problem. Six, two big sparks seriously damaged the solid state RF driver for the high-voltage generation, rendering the AMS system incapable of applying the high voltage of 2.5 MV used for 14C measurements. We replaced a damaged coil at the final part of high-voltage power supply for the repair. As a consequence of these numerous problems, were only able to process 466 graphite targets in 2016. We also carried out a number of application programs for 14C measurements at Nagoya University in 2016. Some of the results are reported in these Proceedings.", "subitem_description_type": "Abstract"}]}, "item_9_identifier_registration": {"attribute_name": "ID\u767b\u9332", "attribute_value_mlt":
