Using an impulse waveform voltage, which has broadband frequency components, we constructed an ultrashort pulsed radar reflectometer with 28 channels in X-, Ka-, and U-band frequency components. The effect of the bandwidth of an inline band-pass filter was investigated, and was optimized. For a multiple-channel and multiple-frequency band system, a new switching technique and multiplexer were developed. Using the Abel inversion method, the reconstructed electron density profile was obtained from the delay time as a function of the probing frequency. Good agreement with other diagnostics was obtained.","subitem_description_type":"Abstract"}]},"item_2_publisher_8":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"プラズマ・核融合学会"}]},"item_2_relation_14":{"attribute_name":"DOI","attribute_value_mlt":[{"subitem_relation_type_id":{"subitem_relation_type_id_text":"10.1585/pfr.3.018","subitem_relation_type_select":"DOI"}}]},"item_2_rights_15":{"attribute_name":"権利","attribute_value_mlt":[{"subitem_rights":"? 2008 The Japan Society of Plasma Science and Nuclear Fusion Research"}]},"item_creator":{"attribute_name":"著者","attribute_type":"creator","attribute_value_mlt":[{"creatorNames":[{"creatorName":"TOKUZAWA,  Tokihiko","creatorNameLang":"en"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"KAWAHATA,  Kazuo","creatorNameLang":"en"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"ITO,  Yasuhiko","creatorNameLang":"en"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"TANAKA,  Kenji","creatorNameLang":"en"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"YAMADA,  Ichihiro","creatorNameLang":"en"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"LHD, Experimental Group","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":"2016-03-11"}],"displaytype":"detail","filename":"pfr2008_03-018.pdf","filesize":[{"value":"2.5 MB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"pfr2008_03-018.pdf","url":"https://nifs-repository.repo.nii.ac.jp/record/210/files/pfr2008_03-018.pdf"},"version_id":"a8e744b6-2039-40e8-ba79-b331908d992f"}]},"item_keyword":{"attribute_name":"キーワード","attribute_value_mlt":[{"subitem_subject":"impulse","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"microwave radar","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"electron density profile","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"microwave reflectometer","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"LHD","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":"Development of a Plasma Diagnostics System Using an Impulse Waveform Voltage","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"Development of a Plasma Diagnostics System Using an Impulse Waveform Voltage","subitem_title_language":"en"}]},"item_type_id":"2","owner":"3","path":["7"],"pubdate":{"attribute_name":"公開日","attribute_value":"2011-03-24"},"publish_date":"2011-03-24","publish_status":"0","recid":"210","relation_version_is_last":true,"title":["Development of a Plasma Diagnostics System Using an Impulse Waveform Voltage"],"weko_creator_id":"3","weko_shared_id":-1},"updated":"2023-06-20T20:47:32.887609+00:00"}
