Every instantaneous emission of visible light due to discharge occurred at the side of stacked crystals during heating and cooling cycle between room temperature and 400 K under atmospheric pressure. Discharge frequency on a stacked unit made of equal-sized four pieces (type-A) was five times more than that on a unit made of irregularlysized pieces (type-C). Discharge occurred possibly at narrow gap between two pieces of platelike single crystal. During heating process up to ca. 400 K under 1 or 10 - 4 Pa, spike-like X-ray emission for a few seconds through one minute occurred repeatedly on both type-A and -C units. The maximum energy of emitted X-ray was independent on both degree of vacuum and shape of stacked plate-like LiTaO3 single crystal. Discharge on type-A unit was suppressed by coating of stacked crystals with dielectric grease whereas high voltage generated on the coated unit. Origin of spike-like X-ray emission and discharge on stacked LiTaO3 units was discussed.","subitem_description_language":"en","subitem_description_type":"Abstract"}]},"item_10001_publisher_8":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"日本分析化学会","subitem_publisher_language":"ja"}]},"item_10001_rights_15":{"attribute_name":"権利情報","attribute_value_mlt":[{"subitem_rights":"©公益社団法人日本分析化学会X線分析研究懇談会","subitem_rights_language":"ja"}]},"item_10001_source_id_9":{"attribute_name":"収録物ID","attribute_value_mlt":[{"subitem_source_identifier":"09117806","subitem_source_identifier_type":"ISSN"},{"subitem_source_identifier":"AN0000592X","subitem_source_identifier_type":"NCID"}]},"item_10001_version_type_20":{"attribute_name":"出版タイプ","attribute_value_mlt":[{"subitem_version_resource":"http://purl.org/coar/version/c_970fb48d4fbd8a85","subitem_version_type":"VoR"}]},"item_1715043197608":{"attribute_name":"アクセス権","attribute_value_mlt":[{"subitem_access_right":"open access"}]},"item_1723180141928":{"attribute_name":"EID","attribute_value_mlt":[{"subitem_identifier_type":"URI","subitem_identifier_uri":"349096"}]},"item_creator":{"attribute_name":"著者","attribute_type":"creator","attribute_value_mlt":[{"creatorNames":[{"creatorName":"山本, 孝","creatorNameLang":"ja"}],"nameIdentifiers":[{"nameIdentifier":"355","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"宮園, 拓自","creatorNameLang":"ja"},{"creatorName":"Miyazono, Takuji","creatorNameLang":"en"}]},{"creatorNames":[{"creatorName":"栗本, 彰人","creatorNameLang":"ja"},{"creatorName":"Kurimoto, Akihito","creatorNameLang":"en"}]}]},"item_files":{"attribute_name":"ファイル情報","attribute_type":"file","attribute_value_mlt":[{"accessrole":"open_access","date":[{"dateType":"Available","dateValue":"2019-04-05"}],"displaytype":"detail","filename":"axca_50_291.pdf","filesize":[{"value":"1000 KB"}],"format":"application/pdf","mimetype":"application/pdf","url":{"objectType":"fulltext","url":"https://tokushima-u.repo.nii.ac.jp/record/2006341/files/axca_50_291.pdf"},"version_id":"8703912a-72d9-441a-abe8-4cc0bf40d34a"}]},"item_keyword":{"attribute_name":"キーワード","attribute_value_mlt":[{"subitem_subject":"積層型焦電結晶","subitem_subject_language":"ja","subitem_subject_scheme":"Other"},{"subitem_subject":"タンタル酸リチウム","subitem_subject_language":"ja","subitem_subject_scheme":"Other"},{"subitem_subject":"X線発生","subitem_subject_language":"ja","subitem_subject_scheme":"Other"},{"subitem_subject":"放電","subitem_subject_language":"ja","subitem_subject_scheme":"Other"},{"subitem_subject":"真空度","subitem_subject_language":"ja","subitem_subject_scheme":"Other"},{"subitem_subject":"Stacked pyroelectric single crystal","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"LiTaO3","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"X-ray emission","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"Discharge","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"Degree of vacuum","subitem_subject_language":"en","subitem_subject_scheme":"Other"}]},"item_language":{"attribute_name":"言語","attribute_value_mlt":[{"subitem_language":"jpn"}]},"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":"形状の異なる焦電結晶積層体によるX線発生挙動および放電特性","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"形状の異なる焦電結晶積層体によるX線発生挙動および放電特性","subitem_title_language":"ja"}]},"item_type_id":"40001","owner":"7","path":["1713853295607"],"pubdate":{"attribute_name":"PubDate","attribute_value":"2019-04-05"},"publish_date":"2019-04-05","publish_status":"0","recid":"2006341","relation_version_is_last":true,"title":["形状の異なる焦電結晶積層体によるX線発生挙動および放電特性"],"weko_creator_id":"7","weko_shared_id":-1},"updated":"2024-10-29T00:23:00.125769+00:00"}
