Self-reversal was observed in the spectral profile when the plasma density was increased with repetitive injection of hydrogen pellets. A one-dimensional radiation transport model was used for creating the Lyman-α spectral profile, for which an emission and absorption medium with a slab geometry and constant plasma parameters were assumed. The population density of the n = 2 level generally has a peaked spatial profile even with constant ground state density because of the reabsorption effect which is essential for the emergence of self-reversal in the spectral profile. We used the n = 2 level population distribution in the medium by Molisch et al. [Radiation Trapping in Atomic Vapours, Oxford University, Oxford, 1998] and evaluated the Lyman-α spectral profile as a function of the optical thickness. The observed line profile was found to be well fitted, for example, with a ground state density of 5.2 × 1018 m?3 and a medium thickness of 10 cm when a Lorentzian profile having a full width at half maximum of 0.0018 nm is adopted for the emission and absorption coefficients.","subitem_description_type":"Abstract"}]},"item_2_publisher_8":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"The Japan Society of Plasma Science and Nuclear Fusion Research"}]},"item_2_relation_14":{"attribute_name":"DOI","attribute_value_mlt":[{"subitem_relation_type":"isIdenticalTo","subitem_relation_type_id":{"subitem_relation_type_id_text":"<doi>info:doi/10.1585/pfr.5.S2089</doi> ","subitem_relation_type_select":"DOI"}}]},"item_2_relation_17":{"attribute_name":"関連サイト","attribute_value_mlt":[{"subitem_relation_name":[{"subitem_relation_name_text":"Publisher version"}],"subitem_relation_type_id":{"subitem_relation_type_id_text":"http://www.jspf.or.jp/PFR/PFR_articles/pfr2010S2/pfr2010_05-S2089.html","subitem_relation_type_select":"URI"}}]},"item_2_rights_15":{"attribute_name":"権利","attribute_value_mlt":[{"subitem_rights":"? 2010 The Japan Society of Plasma Science and Nuclear Fusion Research"}]},"item_2_source_id_9":{"attribute_name":"ISSN","attribute_value_mlt":[{"subitem_source_identifier":"18806821","subitem_source_identifier_type":"ISSN"}]},"item_2_version_type_20":{"attribute_name":"著者版フラグ","attribute_value_mlt":[{"subitem_version_resource":"http://purl.org/coar/version/c_970fb48d4fbd8a85","subitem_version_type":"VoR"}]},"item_creator":{"attribute_name":"著者","attribute_type":"creator","attribute_value_mlt":[{"creatorAffiliations":[{"affiliationNameIdentifiers":[{"affiliationNameIdentifier":""}],"affiliationNames":[{"affiliationName":""}]}],"creatorNames":[{"creatorName":"GOTO,  Motoshi","creatorNameLang":"en"}],"familyNames":[{}],"givenNames":[{}],"nameIdentifiers":[{}]},{"creatorAffiliations":[{"affiliationNameIdentifiers":[{"affiliationNameIdentifier":""}],"affiliationNames":[{"affiliationName":""}]}],"creatorNames":[{"creatorName":"MORITA,  Shigeru","creatorNameLang":"en"}],"familyNames":[{}],"givenNames":[{}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"GOTO,  Motoshi","creatorNameLang":"en"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"MORITA,  Shigeru","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":"2016-03-23"}],"displaytype":"detail","filename":"pfr2010_05-S2089.pdf","filesize":[{"value":"288.2 kB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"pfr2010_05-S2089.pdf","url":"https://nifs-repository.repo.nii.ac.jp/record/558/files/pfr2010_05-S2089.pdf"},"version_id":"83993cd0-e69c-4cc5-9097-bc8fa7a8ee41"}]},"item_keyword":{"attribute_name":"キーワード","attribute_value_mlt":[{"subitem_subject":"Lyman-α","subitem_subject_scheme":"Other"},{"subitem_subject":"self-reversal","subitem_subject_scheme":"Other"},{"subitem_subject":"reabsorption effect","subitem_subject_scheme":"Other"},{"subitem_subject":"LHD","subitem_subject_scheme":"Other"},{"subitem_subject":"intrnal diffusion barrier","subitem_subject_scheme":"Other"},{"subitem_subject":"Lyman-α","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"self-reversal","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"reabsorption effect","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"LHD","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"intrnal diffusion barrier","subitem_subject_language":"en","subitem_subject_scheme":"Other"}]},"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":"journal article","resourceuri":"http://purl.org/coar/resource_type/c_6501"}]},"item_title":"Self-Reversal in Hydrogen Lyman-α Line Profile","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"Self-Reversal in Hydrogen Lyman-α Line Profile"},{"subitem_title":"Self-Reversal in Hydrogen Lyman-α Line Profile","subitem_title_language":"en"}]},"item_type_id":"2","owner":"3","path":["7"],"pubdate":{"attribute_name":"公開日","attribute_value":"2011-05-02"},"publish_date":"2011-05-02","publish_status":"0","recid":"558","relation_version_is_last":true,"title":["Self-Reversal in Hydrogen Lyman-α Line Profile"],"weko_creator_id":"3","weko_shared_id":3},"updated":"2023-09-26T05:53:54.838294+00:00"}
