The plates in the binary filter system are made of poly (methyl methacrylate) (PMMA), which acts as a water-equivalent material. To evaluate the water-equivalent thicknesses of the PMMA plates, Bragg curves of an 80 MeV proton beam in a water phantom were measured with each PMMA plate or without any plates. The water-equivalent thicknesses of the filters were derived as displacements of Bragg peak with an accuracy of 10 micrometer. The mean ratio between real and water-equivalent thicknesses of the plates was calculated to be about 1.16.","subitem_description_type":"Abstract"}]},"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":"北村, 尚"}],"nameIdentifiers":[{"nameIdentifier":"570988","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"北村 尚","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"570989","nameIdentifierScheme":"WEKO"}]}]},"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":"article","resourceuri":"http://purl.org/coar/resource_type/c_6501"}]},"item_title":"放医研サイクロトロン用バイナリフィルターの水等価厚測定","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"放医研サイクロトロン用バイナリフィルターの水等価厚測定"}]},"item_type_id":"10004","owner":"1","path":["7"],"pubdate":{"attribute_name":"公開日","attribute_value":"2012-12-10"},"publish_date":"2012-12-10","publish_status":"0","recid":"55802","relation_version_is_last":true,"title":["放医研サイクロトロン用バイナリフィルターの水等価厚測定"],"weko_creator_id":"1","weko_shared_id":-1},"updated":"2023-05-15T22:45:14.176313+00:00"}
