The CCD device we used is a product of Sharp Corp. named LZ22187 which is widely used in optical region. This device is operated in the same condition as that of a commercial use with the exception that the cover glass is removed for the X-ray to reach the photo diode. It is an interline-transfer type device with 386×488 elements while we summed up internally every two adjacent elements. We exposed the X-ray to the CCD at about -60℃. The energy resolution is about 900 ev (FWHM) which is mainly determined not by the incident X-ray energy but by the read-out noise. We found that this device could yield sufficient information for two dimensional image. The spatial resolution is up to individual element size (23×27μm). The efficiency for the X-ray is much superior to that of the film. We discuss the possibility to improve the characteristics of the CCD in X-ray energy region.","subitem_description_type":"Other"}]},"item_9_description_32":{"attribute_name":"資料番号","attribute_value_mlt":[{"subitem_description":"資料番号: SA0166839000","subitem_description_type":"Other"}]},"item_9_publisher_8":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"宇宙科学研究所"}]},"item_9_publisher_9":{"attribute_name":"出版者（英）","attribute_value_mlt":[{"subitem_publisher":"Institute of Space and Astronautical Science"}]},"item_9_source_id_21":{"attribute_name":"ISSN","attribute_value_mlt":[{"subitem_source_identifier":"0285-9920","subitem_source_identifier_type":"ISSN"}]},"item_9_source_id_24":{"attribute_name":"書誌レコードID","attribute_value_mlt":[{"subitem_source_identifier":"AN00354485","subitem_source_identifier_type":"NCID"}]},"item_9_text_6":{"attribute_name":"著者所属","attribute_value_mlt":[{"subitem_text_value":"大阪大学理学部"},{"subitem_text_value":"大阪大学理学部"},{"subitem_text_value":"キャノン株式会社"}]},"item_creator":{"attribute_name":"著者","attribute_type":"creator","attribute_value_mlt":[{"creatorNames":[{"creatorName":"水方, 勝哉"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"常深, 博"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"平松, 誠"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"MIZUKATA, K.","creatorNameLang":"en"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"TSUNEMI, H.","creatorNameLang":"en"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"HIRAMATSU, M.","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":"2020-01-24"}],"displaytype":"detail","filename":"SA0166839.pdf","filesize":[{"value":"903.8 kB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"SA0166839.pdf","url":"https://jaxa.repo.nii.ac.jp/record/33000/files/SA0166839.pdf"},"version_id":"d0aebe0c-6ecd-4d73-80fa-c9eb3a15e9ad"}]},"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":"departmental bulletin paper","resourceuri":"http://purl.org/coar/resource_type/c_6501"}]},"item_title":"可視光用 CCD の軟 X 線に対する特性","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"可視光用 CCD の軟 X 線に対する特性"}]},"item_type_id":"9","owner":"1","path":["1890","1912"],"pubdate":{"attribute_name":"公開日","attribute_value":"2015-03-26"},"publish_date":"2015-03-26","publish_status":"0","recid":"33000","relation_version_is_last":true,"title":["可視光用 CCD の軟 X 線に対する特性"],"weko_creator_id":"1","weko_shared_id":-1},"updated":"2023-06-21T00:18:28.803511+00:00"}
