These cosmicrays cause surface and bulk radiation effects, resulting in degradation of detector performance. Quantitativeevaluation of radiation hardness is essential in development of X-ray detectors for astronomical satellites. Weperformed proton irradiation experiments on newly developed X-ray detectors called XRPIX based on silicon-on-insulator technology at HIMAC in National Institute of Radiological Sciences. We irradiated 6 MeV protonswith a total dose of 0.5 krad, equivalent to 6 years irradiation in orbit. As a result, the gain increases by 0.2%and the energy resolution degrades by 0.5%. Finally we irradiated protons up to 20 krad and found that detectorperformance degraded significantly at 5 krad. With 5 krad irradiation corresponding to 60 years in orbit, thegain increases by 0.7% and the energy resolution worsens by 10%. By decomposing into noise components, wefound that the increase of the circuit noise is dominant in the degradation of the energy resolution.","subitem_description_type":"Abstract"}]},"item_8_relation_14":{"attribute_name":"DOI","attribute_value_mlt":[{"subitem_relation_type_id":{"subitem_relation_type_id_text":"10.1016/j.nima.2018.09.057","subitem_relation_type_select":"DOI"}}]},"item_8_relation_17":{"attribute_name":"関連サイト","attribute_value_mlt":[{"subitem_relation_type_id":{"subitem_relation_type_id_text":"https://www.sciencedirect.com/science/article/pii/S0168900218312014?via%3Dihub","subitem_relation_type_select":"URI"}}]},"item_8_source_id_9":{"attribute_name":"ISSN","attribute_value_mlt":[{"subitem_source_identifier":"0168-9002","subitem_source_identifier_type":"ISSN"}]},"item_access_right":{"attribute_name":"アクセス権","attribute_value_mlt":[{"subitem_access_right":"metadata only access","subitem_access_right_uri":"http://purl.org/coar/access_right/c_14cb"}]},"item_creator":{"attribute_name":"著者","attribute_type":"creator","attribute_value_mlt":[{"creatorNames":[{"creatorName":"Yarita, Keigo"}],"nameIdentifiers":[{"nameIdentifier":"1001927","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Kohmura, Takayoshi"}],"nameIdentifiers":[{"nameIdentifier":"1001928","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Hagino, Kouichi"}],"nameIdentifiers":[{"nameIdentifier":"1001929","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Kogiso, Taku"}],"nameIdentifiers":[{"nameIdentifier":"1001930","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Oono, Kenji"}],"nameIdentifiers":[{"nameIdentifier":"1001931","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Hamano, Tsuyoshi"}],"nameIdentifiers":[{"nameIdentifier":"1001932","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"people, Others,many"}],"nameIdentifiers":[{"nameIdentifier":"1001933","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Tsuyoshi, Hamano","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"1001934","nameIdentifierScheme":"WEKO"}]}]},"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":"Proton radiation damage experiment for X-ray SOI pixel detectors","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"Proton radiation damage experiment for X-ray SOI pixel detectors"}]},"item_type_id":"8","owner":"1","path":["1"],"pubdate":{"attribute_name":"公開日","attribute_value":"2019-11-28"},"publish_date":"2019-11-28","publish_status":"0","recid":"77670","relation_version_is_last":true,"title":["Proton radiation damage experiment for X-ray SOI pixel detectors"],"weko_creator_id":"1","weko_shared_id":-1},"updated":"2023-05-15T19:35:57.922006+00:00"}
