Main improvements of the 2nd-generation Tandetron compared with the old GIC(General Ionex Corporation)-Tandetron are : (1) a high intensity cesium sputter ion source is equipped with the new system, so that the ^\u003c14\u003eC 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 ^\u003c12\u003eC-, ^\u003c13\u003eC- and ^\u003c14\u003eC- are 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^\u003c3+\u003e 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 ^\u003c13\u003eC^\u003c3+\u003e ions stabilizes terminal voltage, which provides us highly stable isotope-ratio measurement. (4) a gas ionization detector measures E and E_\u003cresidual\u003e of incoming ions, to separate ^\u003c14\u003eC^\u003c3+\u003e ions from various background ions. Provided that the background ions are rejected efficiently, ^\u003c14\u003eC 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. These improvements are discussed here in detail. As the results of those improvements stated above, the highest performances in the ^\u003c14\u003eC measurements with the new Tandetron is : (1) a measurement error of ^\u003c14\u003eC 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 1 mg ; (2) a full automatic measurement can be routinely performed ; (3) more than 3,000 samples can be measured annually.", "subitem_description_type": "Abstract"}]}, "item_9_description_5": {"attribute_name": "内容記述", "attribute_value_mlt": [{"subitem_description": "第10回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9 (1997)年度)報告 ｢最新型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(II)｣", "subitem_description_type": "Other"}]}, "item_9_identifier_registration": {"attribute_name": "ID登録", "attribute_value_mlt": [{"subitem_identifier_reg_text": "10.18999/10.19999/sumrua.9.27", "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"}]}, "item_9_relation_43": {"attribute_name": "異版である", "attribute_value_mlt": [{"subitem_relation_type": "isVersionOf", "subitem_relation_type_id": {"subitem_relation_type_id_text": "http://ci.nii.ac.jp/naid/110001136041/", "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": "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"}]}, "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_creator": {"attribute_name": "著者", "attribute_type": "creator", "attribute_value_mlt": [{"creatorNames": [{"creatorName": "中村, 俊夫"}], "nameIdentifiers": [{"nameIdentifier": "80479", "nameIdentifierScheme": "WEKO"}]}, {"creatorNames": [{"creatorName": "Nakamura, Toshio"}], "nameIdentifiers": [{"nameIdentifier": "80480", "nameIdentifierScheme": "WEKO"}]}, {"creatorNames": [{"creatorName": "パルス, ルディ"}], "nameIdentifiers": [{"nameIdentifier": "80481", "nameIdentifierScheme": "WEKO"}]}, {"creatorNames": [{"creatorName": "Pals, Ludi"}], "nameIdentifiers": [{"nameIdentifier": "80482", "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", "download_preview_message": "", "file_order": 0, "filename": "KJ00002410045.pdf", "filesize": [{"value": "993.5 kB"}], "format": "application/pdf", "future_date_message": "", "is_thumbnail": false, "licensetype": "license_free", "mimetype": "application/pdf", "size": 993500.0, "url": {"label": "KJ00002410045.pdf", "url": "https://nagoya.repo.nii.ac.jp/record/11500/files/KJ00002410045.pdf"}, "version_id": "08f0660b-4463-4379-9b19-4ef6894009a3"}]}, "item_keyword": {"attribute_name": "キーワード", "attribute_value_mlt": [{"subitem_subject": "加速器質量分析", "subitem_subject_scheme": "Other"}, {"subitem_subject": "タンデトロン", "subitem_subject_scheme": "Other"}, {"subitem_subject": "高輝度セシウムスパッタ負イオン源", "subitem_subject_scheme": "Other"}, {"subitem_subject": "同位体同時入射システム", "subitem_subject_scheme": "Other"}, {"subitem_subject": "リコンビネーター", "subitem_subject_scheme": "Other"}, {"subitem_subject": "ビームプロフィルモニタ", "subitem_subject_scheme": "Other"}, {"subitem_subject": "電離箱検出器", "subitem_subject_scheme": "Other"}]}, "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": "名古屋大学に設置されているGIC社およびHVEE社製の2台のタンデトロン加速器質量分析計の現状", "item_titles": {"attribute_name": "タイトル", "attribute_value_mlt": [{"subitem_title": "名古屋大学に設置されているGIC社およびHVEE社製の2台のタンデトロン加速器質量分析計の現状"}]}, "item_type_id": "9", "owner": "1", "path": ["1228"], "permalink_uri": "https://doi.org/10.18999/10.19999/sumrua.9.27", "pubdate": {"attribute_name": "公開日", "attribute_value": "2010-05-19"}, "publish_date": "2010-05-19", "publish_status": "0", "recid": "11500", "relation": {}, "relation_version_is_last": true, "title": ["名古屋大学に設置されているGIC社およびHVEE社製の2台のタンデトロン加速器質量分析計の現状"], "weko_shared_id": null}
