The samples comprised the materials used for conventional vacuum systems. Ad/absorption tritium could be detected as RD (room temperature desorption), SR (surface residuum) and HD (high temperature desorption) species. With respect to organic polymers, only HT molecules dissolved in the samples were responsible for the RD, SR and HD. As for other materials, however, the RD species was revealed to be physically adsorbed HTO. The HD species formed a peak at about 460K for each material except organic polymers. It appeared to be adsorbed tritium, but desorbed as a condensable gas at liquid nitrogen temperature. It was, however, not soluble in water. Its chemical forms and formation mechanisms were left as open question. The SR species appeared to be a part of HD. The order of adsorption amounts was as follows: [Epoxy resin, FRP (Fiber reinforced plastics)] > [Ni (Nickel)] > [Cr (Chromium), Fe (Iron), SS304 (Stainless steel), A2219 (Aluminum alloy)] > [h-BN (Boron nitride), SiC (Silicon carbide), ASS (SS304 passivated by anodic oxidation layers), BSS (SS304 passivated by h-BN segregation layers)]. This order was considerably different from that observed for clean surfaces. In addition, the adsorption amounts for metals/alloy were about two orders of magnitude smaller than those reported for clean metal surfaces. This discrepancy in results in apparently due to the presence of oxides and contamination layers over the samples used. Nevertheless, it was found that the passivation of SS304 with anodic oxidation and/or h-BN segregation layers should be quite valid to decrease the tritium inventory and/or contamination on/of the material walls of tritium handling systems.","subitem_description_type":"Abstract"}]},"item_3_description_40":{"attribute_name":"資源タイプ(DSpace)","attribute_value_mlt":[{"subitem_description":"Article","subitem_description_type":"Other"}]},"item_3_full_name_3":{"attribute_name":"著者別名","attribute_value_mlt":[{"nameIdentifiers":[{"nameIdentifier":"21840","nameIdentifierScheme":"WEKO"}],"names":[{"name":"Cowgill, Donald F."}]},{"nameIdentifiers":[{"nameIdentifier":"21841","nameIdentifierScheme":"WEKO"}],"names":[{"name":"MIYAKE, Hitoshi"}]},{"nameIdentifiers":[{"nameIdentifier":"21842","nameIdentifierScheme":"WEKO"}],"names":[{"name":"MATSUYAMA, Masao"}]},{"nameIdentifiers":[{"nameIdentifier":"21843","nameIdentifierScheme":"WEKO"}],"names":[{"name":"ASHIDA, Kan"}]},{"nameIdentifiers":[{"nameIdentifier":"21844","nameIdentifierScheme":"WEKO"}],"names":[{"name":"WATANABE, Kuniaki"}]}]},"item_3_identifier_registration":{"attribute_name":"ID登録","attribute_value_mlt":[{"subitem_identifier_reg_text":"10.15099/00006384","subitem_identifier_reg_type":"JaLC"}]},"item_3_publisher_33":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"富山大学水素同位体機能研究センター"}]},"item_3_source_id_10":{"attribute_name":"書誌レコードID","attribute_value_mlt":[{"subitem_source_identifier":"AN10443060","subitem_source_identifier_type":"NCID"}]},"item_3_source_id_8":{"attribute_name":"ISSN","attribute_value_mlt":[{"subitem_source_identifier":"0916-8486","subitem_source_identifier_type":"ISSN"}]},"item_3_version_type_16":{"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":"三宅, 均"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"松山, 政夫"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"芦田, 完"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"渡辺, 国昭"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"Cowgill, Donald F."}],"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":"detail","filename":"annual_report10-4.pdf","filesize":[{"value":"677.4 kB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"annual_report10-4.pdf","url":"https://toyama.repo.nii.ac.jp/record/6390/files/annual_report10-4.pdf"},"version_id":"0aa81214-9fb7-44c6-bc82-06fb3f19d5ab"}]},"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":"departmental bulletin paper","resourceuri":"http://purl.org/coar/resource_type/c_6501"}]},"item_title":"未処理の真空材料に対するトリチウムの吸着","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"未処理の真空材料に対するトリチウムの吸着"}]},"item_type_id":"3","owner":"3","path":["790"],"pubdate":{"attribute_name":"公開日","attribute_value":"2007-10-03"},"publish_date":"2007-10-03","publish_status":"0","recid":"6390","relation_version_is_last":true,"title":["未処理の真空材料に対するトリチウムの吸着"],"weko_creator_id":"3","weko_shared_id":3},"updated":"2023-07-25T15:42:33.222921+00:00"}
