Co.) is easy to handle and owns a less LET-dependent glow peak which is potential for measurement in heavy charged particle (HCP) therapy beam.   However, the sensitivity of is not stable enough for implantation in radiotherapy field. Therefore, a TLD made by chromium-doped alumina (A10, Chibacera Mfg. Co.)  was developed to improve the sensitivity.\nPurpose: This study aims to provide basic dosimetric properties of A10.  \nMaterial and methods: To obtain the thermal luminescence (TL) efficiency, A10 were irradiated using a 160 MeV/u proton beam, a 150 MeV helium beam, a 290 MeV/u carbon beam, a 400 MeV/u Neon beam and a 500 MeV/u Argon beam.  TL efficiency was normalized by a 6MV X-ray.  A10 was heated to 400 oC at a heating rate of 0.2 degree per second and the glow curves were read by an in-house developed readout system.   To improve the accuracy, the timeline of the readout procedure was consistent for each experiment in the present study.\nResults: The dose to response curve of A10 was linear in the range of 0.5-5 Gy for each beam but the slope was different to each other.  The TL efficiency of A10 increased from 0.84 to 1.18 at LET range from 0.5 keV/μm to 13.2 keV/μm and decreased to 0.6 when keV/μm was 197 keV/μm.","subitem_description_type":"Abstract"}]},"item_10005_description_6":{"attribute_name":"会議概要（会議名, 開催地, 会期, 主催者等）","attribute_value_mlt":[{"subitem_description":"World Congress on Medical Physics & Biomedical Engineering","subitem_description_type":"Other"}]},"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":"Chang, Weishan"}],"nameIdentifiers":[{"nameIdentifier":"657051","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Koba, Yusuke"}],"nameIdentifiers":[{"nameIdentifier":"657052","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Shimomura, Risa"}],"nameIdentifiers":[{"nameIdentifier":"657053","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Shinsho, Kiyomitsu"}],"nameIdentifiers":[{"nameIdentifier":"657054","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Matsumoto, Kazuki"}],"nameIdentifiers":[{"nameIdentifier":"657055","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Ushiba, Hiroki"}],"nameIdentifiers":[{"nameIdentifier":"657056","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Ando, Takayuki"}],"nameIdentifiers":[{"nameIdentifier":"657057","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"張 維珊","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"657058","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"古場 裕介","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"657059","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":"conference object","resourceuri":"http://purl.org/coar/resource_type/c_c94f"}]},"item_title":"Thermal luminescence efficiency of  Al2O3:Cr ceramic to heavy charged particle","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"Thermal luminescence efficiency of  Al2O3:Cr ceramic to heavy charged particle"}]},"item_type_id":"10005","owner":"1","path":["29"],"pubdate":{"attribute_name":"公開日","attribute_value":"2018-06-11"},"publish_date":"2018-06-11","publish_status":"0","recid":"66824","relation_version_is_last":true,"title":["Thermal luminescence efficiency of  Al2O3:Cr ceramic to heavy charged particle"],"weko_creator_id":"1","weko_shared_id":-1},"updated":"2023-05-15T20:44:30.113855+00:00"}
