Two sets of the similar HVEE AMS system have been installed successfully at University of Groningen, Holland, and at University of Christian-Albrechts, Kiel, Germany. They have already proved excellent performances in carbon-isotope-ratio measurements : reproducibility of ^<13>C/^<12>C ratio as ±0.1% ; error and reproducibility of ^<14>C/^<12>C ratio as ±0.15-0.22% and ±0.3%, respectively. Main improvements of the 2nd-generation Tandetron compared with the old Tandetron are : (1) a high intensity cesium sputter ion source is equipped with the new system, so that the ^<14> counting rate is almost one order higher than that for the old system. In addition, since up to 59 targets can be loaded at a time, measurements can be conducted more efficiently. (2) carbon isotopes ^<12>C^-, ^<13>C^- and ^<14>C^- can be injected into a tandem accelerator simultaneously, by using a recombinator system, which will archive high accuracy measurements of the carbon isotope ratio. (3) the terminal voltage of the accelerator is 2.5MV, which gives the maximum yield in producing C^<3+> from C^- in the charge exchange process of the tandem accelerator. In addition, a slit feedback system with a position sensitive Faraday cup to monitor the energy of accelerated ^<13>C^<3+> ions stabilizes terminal voltage, which provides us highly stable isotope-ratio measurement. (4) a heavy ion detector measures E and E_<residual> of incoming ions, to separate ^<14>C^<3+> ions from various background ions. Provided that the background ions are rejected efficiently, ^<14>C ages older than 60,000 will be measurable with this system. (5) A computer program is equipped with the system which controls the carbon-isotope-ratio measurement for multi-samples automatically. This provides us a high-efficient measurement without any hard works of operation staff. As the results of those improvements stated above, the highest performances is the ^<14>C measurements with the new Tandetron is : (1) a measurement error of ^<14>C age can be as small as ±20 years with a measurement time of a few tens of minutes for a carbon sample of less than 1mg ; (2) a full automatic measurement can be routinely performed ; (3) more than 3,000 samples can be measured annually. The new system will be used efficiently and speedy by many domestic researchers as well as by those outside of the university, if graphite targets are provided to us which are prepared from raw carbonaceous materials by researchers themselves.","subitem_description_language":"en","subitem_description_type":"Abstract"}]},"item_9_description_5":{"attribute_name":"内容記述","attribute_value_mlt":[{"subitem_description":"名古屋大学タンデトロン加速器質量分析計シンポジウム(平成8年(1996年度)報告 ｢第2世代タンデトロン加速器質量分析計(加速器年代測定システム)による高精度･高分解能14C年代測定の利用分野･方法の開拓｣ Proceedings of Symposium on Researches with a Tandetron Accelerator Mass Spectrometer at Nagoya University in 1996“Studies on New Fields and New Methods of Applications of High-Precision and High-Accuracy Radiocarbon Dating with a Second-Generation Tandetron Accelerator Mass Spectrometer at Nagoya University”日時:1997 (平成9)年3月10日 場所:名古屋大学年代測定資料研究センター古川総合研究資料館講義室","subitem_description_language":"ja","subitem_description_type":"Other"}]},"item_9_identifier_registration":{"attribute_name":"ID登録","attribute_value_mlt":[{"subitem_identifier_reg_text":"10.18999/sumrua.8.5","subitem_identifier_reg_type":"JaLC"}]},"item_9_publisher_32":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"名古屋大学年代測定資料研究センター 天然放射性元素測定小委員会","subitem_publisher_language":"ja"}]},"item_9_relation_43":{"attribute_name":"関連情報","attribute_value_mlt":[{"subitem_relation_type":"isVersionOf","subitem_relation_type_id":{"subitem_relation_type_id_text":"http://ci.nii.ac.jp/naid/110000476001/","subitem_relation_type_select":"URI"}}]},"item_9_rights_12":{"attribute_name":"権利","attribute_value_mlt":[{"subitem_rights":"名古屋大学年代測定資料研究センター 天然放射性元素測定小委員会","subitem_rights_language":"ja"},{"subitem_rights":"本文データは学協会の許諾に基づきCiNiiから複製したものである","subitem_rights_language":"ja"}]},"item_9_select_15":{"attribute_name":"著者版フラグ","attribute_value_mlt":[{"subitem_select_item":"publisher"}]},"item_9_text_14":{"attribute_name":"フォーマット","attribute_value_mlt":[{"subitem_text_value":"application/pdf"}]},"item_access_right":{"attribute_name":"アクセス権","attribute_value_mlt":[{"subitem_access_right":"open access","subitem_access_right_uri":"http://purl.org/coar/access_right/c_abf2"}]},"item_creator":{"attribute_name":"著者","attribute_type":"creator","attribute_value_mlt":[{"creatorNames":[{"creatorName":"中村, 俊夫","creatorNameLang":"ja"}],"nameIdentifiers":[{"nameIdentifier":"80261","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Nakamura, Toshio","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"80262","nameIdentifierScheme":"WEKO"}]}]},"item_files":{"attribute_name":"ファイル情報","attribute_type":"file","attribute_value_mlt":[{"accessrole":"open_date","date":[{"dateType":"Available","dateValue":"2018-02-20"}],"displaytype":"detail","filename":"KJ00000187779.pdf","filesize":[{"value":"856.1 kB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"KJ00000187779.pdf","objectType":"fulltext","url":"https://nagoya.repo.nii.ac.jp/record/11451/files/KJ00000187779.pdf"},"version_id":"2ba2119c-11ad-4fb1-aa60-e798e265870f"}]},"item_language":{"attribute_name":"言語","attribute_value_mlt":[{"subitem_language":"jpn"}]},"item_resource_type":{"attribute_name":"資源タイプ","attribute_value_mlt":[{"resourcetype":"departmental bulletin paper","resourceuri":"http://purl.org/coar/resource_type/c_6501"}]},"item_title":"名古屋大学タンデトロン2号機の性能と運用","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"名古屋大学タンデトロン2号機の性能と運用","subitem_title_language":"ja"}]},"item_type_id":"9","owner":"17","path":["1227"],"pubdate":{"attribute_name":"PubDate","attribute_value":"2010-05-14"},"publish_date":"2010-05-14","publish_status":"0","recid":"11451","relation_version_is_last":true,"title":["名古屋大学タンデトロン2号機の性能と運用"],"weko_creator_id":"17","weko_shared_id":-1},"updated":"2023-11-13T06:51:31.997572+00:00"}
