Measurement of the detector response well above this regime is important for our application\nmeasuring the heavy ion exposure of NASA astronauts. We find that high input charges produce\na double pulse structure in the Timepix front end which creates a taxonomy of different clusters\nwhich are observed at accelerators, but not in typical operation on orbit. We investigate the LET\nresponse of the Timepix to different heavy ion species and find that for a given polar angle the so called ‘volcano effect’ can be compensated with a simple power law model. We also characterize the pixel response of the Timepix using mono-energetic stopping protons and derive a per pixel calibration method for correction of the pixel response up to about 8 MeV. We conclude that with an appropriate calibration procedure the Timepix can correctly measure the LET values in excess of 500 keVμm????1 in Silicon for tracks with a polar angle exceeding 60°, corresponding to the entirety of the cosmic ray spectrum up to Nickel.","subitem_description_type":"Abstract"}]},"item_8_publisher_8":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"IOP Publishing "}]},"item_8_relation_14":{"attribute_name":"DOI","attribute_value_mlt":[{"subitem_relation_type_id":{"subitem_relation_type_id_text":"10.1088/1748-0221/13/11/P11014","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://doi.org/10.1088/1748-0221/13/11/P11014","subitem_relation_type_select":"DOI"}}]},"item_8_source_id_9":{"attribute_name":"ISSN","attribute_value_mlt":[{"subitem_source_identifier":"1748-0221","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":"George, S.P."}],"nameIdentifiers":[{"nameIdentifier":"798045","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Kroupa, M."}],"nameIdentifiers":[{"nameIdentifier":"798046","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Wheeler, S."}],"nameIdentifiers":[{"nameIdentifier":"798047","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Kodaira, S."}],"nameIdentifiers":[{"nameIdentifier":"798048","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Kitamura, H."}],"nameIdentifiers":[{"nameIdentifier":"798049","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Tlustos, L."}],"nameIdentifiers":[{"nameIdentifier":"798050","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"T., Campbell-Ricketts"}],"nameIdentifiers":[{"nameIdentifier":"798051","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Stoffle, N.N."}],"nameIdentifiers":[{"nameIdentifier":"798052","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Semones, E."}],"nameIdentifiers":[{"nameIdentifier":"798053","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Pinsky, L."}],"nameIdentifiers":[{"nameIdentifier":"798054","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Kodaira, Satoshi","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"798055","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Kitamura, Hisashi","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"798056","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":"Very high energy calibration of silicon Timepix detectors","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"Very high energy calibration of silicon Timepix detectors"}]},"item_type_id":"8","owner":"1","path":["1"],"pubdate":{"attribute_name":"公開日","attribute_value":"2019-02-06"},"publish_date":"2019-02-06","publish_status":"0","recid":"49556","relation_version_is_last":true,"title":["Very high energy calibration of silicon Timepix detectors"],"weko_creator_id":"1","weko_shared_id":-1},"updated":"2023-05-15T23:51:54.586375+00:00"}
