A space-resolved 3m normal incidence VUV spectrometer and newly designed double-structure impurity pellets for an impurity pellets injector have been developed for this purpose. The Ml transitions are identified by analyzing their Doppler broademing， temporal intensity behavior and spatial intensity distribution.　Wavelengths of these M l transitions are determined with high accuracy and compared with previous experimental and calculated values with detailed spectroscopic analysis of C，Ne and Ar emission lines in range of 250 to 2300&Aring;. The Ml transitions from heavy elements observed here are expected to be useful for visible impurity diagnostics of D-T burning plasmas in the future．<br />　The line intensity ratios of the M l transition to the allowed（E l) transition such as 2s<sup>2</sup>2p<sup>5</sup><sup>2</sup>P<small>3/2</small>-<sup>2</sup>P<small>1/2</small> / 2s<sup>2</sup>2p<sup>5</sup> <sup>2</sup>P<small>3/2</small>-2s2p<sup>6</sup> <sup>2</sup>S<small>1/2</small> (ArX 5533&Aring; / 165&Aring;，TiXIV 2118&Aring; / 122&Aring; and FeXVIII 975&Aring; / 94&Aring;）and 2s2p <sup>3</sup>P<small>1</small>.- <sup>3</sup>P<small>2</small> / 2s<sup>2</sup> <sup>1</sup>S<small>0</small>-2s2p <sup>1</sup>P<small>1</small>（ArXV 5944&Aring; / 221&Aring;）are measured as a function of electron density．Results on the ArX and ArXV are compared with a simple level-population calculation．　As a result，the density dependence of the ratio is well explained mainly by a competition between two decay processes of the collisional de-excitation and the radiative decay due to the forbidden line emission．The effect of fast ions on the M l transition is also considered．","subitem_description_type":"Other"}]},"item_1_description_7":{"attribute_name":"学位記番号","attribute_value_mlt":[{"subitem_description":"総研大甲第1036号","subitem_description_type":"Other"}]},"item_1_select_14":{"attribute_name":"所蔵","attribute_value_mlt":[{"subitem_select_item":"有"}]},"item_1_select_8":{"attribute_name":"研究科","attribute_value_mlt":[{"subitem_select_item":"物理科学研究科"}]},"item_1_select_9":{"attribute_name":"専攻","attribute_value_mlt":[{"subitem_select_item":"10 核融合科学専攻"}]},"item_1_text_10":{"attribute_name":"学位授与年度","attribute_value_mlt":[{"subitem_text_value":"2006"}]},"item_creator":{"attribute_name":"著者","attribute_type":"creator","attribute_value_mlt":[{"creatorNames":[{"creatorName":"KATAI, Ryuji","creatorNameLang":"en"}],"nameIdentifiers":[{}]}]},"item_files":{"attribute_name":"ファイル情報","attribute_type":"file","attribute_value_mlt":[{"accessrole":"open_date","date":[{"dateType":"Available","dateValue":"2016-02-17"}],"displaytype":"simple","filename":"甲1036_要旨.pdf","filesize":[{"value":"441.5 kB"}],"format":"application/pdf","licensetype":"license_11","mimetype":"application/pdf","url":{"label":"要旨・審査要旨","url":"https://ir.soken.ac.jp/record/532/files/甲1036_要旨.pdf"},"version_id":"02a7bebe-d659-4d6d-a164-82e2513912ff"},{"accessrole":"open_date","date":[{"dateType":"Available","dateValue":"2016-02-17"}],"displaytype":"simple","filename":"甲1036_本文.pdf","filesize":[{"value":"5.8 MB"}],"format":"application/pdf","licensetype":"license_11","mimetype":"application/pdf","url":{"label":"本文","url":"https://ir.soken.ac.jp/record/532/files/甲1036_本文.pdf"},"version_id":"1a368c06-4cef-4b9d-a7b9-0e5c6e617c32"}]},"item_language":{"attribute_name":"言語","attribute_value_mlt":[{"subitem_language":"eng"}]},"item_resource_type":{"attribute_name":"資源タイプ","attribute_value_mlt":[{"resourcetype":"thesis","resourceuri":"http://purl.org/coar/resource_type/c_46ec"}]},"item_title":"Spectroscopic study on forbidden magnetic dipole transitions in LHD","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"Spectroscopic study on forbidden magnetic dipole transitions in LHD"},{"subitem_title":"Spectroscopic study on forbidden magnetic dipole transitions in LHD","subitem_title_language":"en"}]},"item_type_id":"1","owner":"1","path":["12"],"pubdate":{"attribute_name":"公開日","attribute_value":"2010-02-22"},"publish_date":"2010-02-22","publish_status":"0","recid":"532","relation_version_is_last":true,"title":["Spectroscopic study on forbidden magnetic dipole transitions in LHD"],"weko_creator_id":"1","weko_shared_id":1},"updated":"2023-06-20T16:01:29.247126+00:00"}
