 note = {Since January 1999, the Nagoya University Tandetron accelerator mass spectrometer（ Tandetron AMS, High Voltage Engineering Europa Model 4130-AMS） has been in operation, and 14C measurements of 30,144 samples were carried out. In FY2022（ April 2022 to February 2023）, 14C measurements of 1,114 samples were completed by now. To operate the Tandetron AMS more systematically and improve the reliability of 14C measurements, some upgrading and maintenances have been carried out: replacement of PLS and interlock algorism modification, maintenance of compressed air supply system, adjustment of C- beamline in the injection system, replacement of telemeter cards and optical cables for AMS control and data transmission, repairment and maintenance of autosampler system, adjustment of high energy side beamline alignment, and the remaking of sample preparation equipment for collaborative research users. In this year, the Nagoya University Tandetron AMS is effectively used for a wide variety of ISEE joint research.},
