Recently oxidation treatment at 200 degrees C was reported as an effective means of reducing Ti outgassing. In this paper, we report our measurement and comparison of the electrical breakdown characteristics of Ti electrodes with different oxidation conditions (without oxidation, oxidation at 200 degrees C, oxidation at 450 degrees C). In addition, we analyzed electrode surfaces before and after breakdown experiments in situ with X-ray photoelectron spectroscopy (XPS). Before oxidation, we machined the electrode's surfaces to the roughness of 0.8 mu m Rmax with diamond turning. Breakdown experiments demonstrated that the breakdown field is highest at the first application of voltage to electrodes with oxidized at 200 degrees C. Before breakdown experiment, surface analysis revealed that all the sample electrodes had a large amount of carbon originating from the hydrocarbons of contaminants, and after the experiments, they revealed that the carbons had disappeared. To obtain breakdown characteristics of electrodes with smoother surfaces, we conducted experiments on electrodes with a surface roughness of 0.05 mu m Ra. For these electrodes, the breakdown field was higher at first breakdown; the repetitions required to achieve saturated breakdown fields were significantly fewer, and the amount of carbon on electrode surfaces before breakdown was less.","subitem_description_type":"Abstract"}]},"item_119_description_29":{"attribute_name":"資源タイプ","attribute_value_mlt":[{"subitem_description":"text","subitem_description_type":"Other"}]},"item_119_description_30":{"attribute_name":"フォーマット","attribute_value_mlt":[{"subitem_description":"application/pdf","subitem_description_type":"Other"}]},"item_119_publisher_11":{"attribute_name":"出版者名","attribute_value_mlt":[{"subitem_publisher":"IEEE-INST ELECTRICAL ELECTRONICS ENGINEERS INC"}]},"item_119_relation_16":{"attribute_name":"DOI","attribute_value_mlt":[{"subitem_relation_type":"isIdenticalTo","subitem_relation_type_id":{"subitem_relation_type_id_text":"info:doi/10.1109/TDEI.2006.1593407","subitem_relation_type_select":"DOI"}}]},"item_119_source_id_14":{"attribute_name":"ISSN","attribute_value_mlt":[{"subitem_source_identifier":"10709878","subitem_source_identifier_type":"ISSN"}]},"item_119_text_27":{"attribute_name":"版","attribute_value_mlt":[{"subitem_text_value":"[出版社版]"}]},"item_119_text_3":{"attribute_name":"著者 ローマ字","attribute_value_mlt":[{"subitem_text_value":"Ito, Y,"},{"subitem_text_value":"Yamano, Yasushi"},{"subitem_text_value":"Kobayashi, Shin'Ichi"},{"subitem_text_value":"Saito, Yoshio"}]},"item_119_text_32":{"attribute_name":"アイテムID","attribute_value_mlt":[{"subitem_text_value":"A1002805"}]},"item_119_text_4":{"attribute_name":"著者 所属","attribute_value_mlt":[{"subitem_text_value":"&EMPTY&"},{"subitem_text_value":"埼玉大学大学院理工学研究科数理電子情報部門"},{"subitem_text_value":"埼玉大学大学院理工学研究科数理電子情報部門"}]},"item_119_text_5":{"attribute_name":"著者 所属(別言語)","attribute_value_mlt":[{"subitem_text_value":"Department of Electrical and Electronic Systems, Saitama University"},{"subitem_text_value":"Department of Electrical and Electronic Systems, Saitama University"},{"subitem_text_value":"Department of Electrical and Electronic Systems, Saitama University"},{"subitem_text_value":"High Energy Accelerator Research Organization"}]},"item_119_text_9":{"attribute_name":"年月次","attribute_value_mlt":[{"subitem_text_value":"2006-2"}]},"item_119_version_type_28":{"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":[{"creatorNames":[{"creatorName":"Ito, Y"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"山納, 康"},{"creatorName":"ヤマノウ, ヤスシ","creatorNameLang":"ja-Kana"}],"nameIdentifiers":[{},{}]},{"creatorNames":[{"creatorName":"小林, 信一"},{"creatorName":"コバヤシ, シンイチ","creatorNameLang":"ja-Kana"}],"nameIdentifiers":[{},{}]}]},"item_files":{"attribute_name":"ファイル情報","attribute_type":"file","attribute_value_mlt":[{"accessrole":"open_date","date":[{"dateType":"Available","dateValue":"2018-01-24"}],"displaytype":"detail","filename":"A1002805.pdf","filesize":[{"value":"423.6 kB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"A1002805.pdf","url":"https://sucra.repo.nii.ac.jp/record/13359/files/A1002805.pdf"},"version_id":"3dde640a-cbb2-40b0-95a5-e0ff3cd7c1be"}]},"item_keyword":{"attribute_name":"キーワード","attribute_value_mlt":[{"subitem_subject":"vacuum breakdown","subitem_subject_scheme":"Other"},{"subitem_subject":"Ti","subitem_subject_scheme":"Other"},{"subitem_subject":"mechanochemical polishing","subitem_subject_scheme":"Other"},{"subitem_subject":"X-ray photoelectron spectroscopy","subitem_subject_scheme":"Other"},{"subitem_subject":"conditioning","subitem_subject_scheme":"Other"},{"subitem_subject":"oxidation","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":"Vacuum electrical breakdown characteristics and surface condition of Ti electrodes with oxidation conditions","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"Vacuum electrical breakdown characteristics and surface condition of Ti electrodes with oxidation conditions"}]},"item_type_id":"119","owner":"3","path":["426"],"pubdate":{"attribute_name":"公開日","attribute_value":"2008-12-03"},"publish_date":"2008-12-03","publish_status":"0","recid":"13359","relation_version_is_last":true,"title":["Vacuum electrical breakdown characteristics and surface condition of Ti electrodes with oxidation conditions"],"weko_creator_id":"3","weko_shared_id":3},"updated":"2023-05-15T19:15:16.216008+00:00"}
