HIMAC BIO is an irradiation room used for experiments related to biology and physics, frequently for calibration of detectors used onboard the International Space Station. To be able to evaluate these experiments, it is essential to know the experimental setup, as well as the beam characteristics, in details. Both narrow and broad parallel heavy ion beams (up to 10 cm), with flat circular profile at the isocenter, can be provided in HIMAC BIO. Such beams are obtained by using beam-line components, similar to those used during radiation therapy. However, these components decrease the energies of the primary beams and are sources of secondary particles. To be able to draw correct conclusions from the experimental results, and to be able to compare the measurements with simulations, it is crucial to know the real energy of the primary ions and the beam composition at the location of the biological samples and the physical detectors. The energies of the primary ions are calculated from Bragg curve measurement with a Markus chamber before each experiment. However, the exact beam composition including the fluence and energies of the secondary fragments and neutrons are usually unknown. The purpose of this paper is to provide detailed information about all the components in the beam line at the HIMAC BIO room to be able to perform particle and heavy ion transport simulations of the beam characteristics. The main sources of secondary particles have been investigated, and the beam composition was calculated by the Monte Carlo code PHITS (Particle and Heavy Ion Transport code System) and compared with measurements using a silicon detector (Liulin) exposed to various monoenergetic and Spread Out Bragg Peak (SOBP) heavy ion beams. We propose a new method of silicon detector calibration using only one heavy ion beam.","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":"16th WRMISS","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":"Ploc, Ondrej"}],"nameIdentifiers":[{"nameIdentifier":"634147","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Uchihori, Yukio"}],"nameIdentifiers":[{"nameIdentifier":"634148","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Kitamura, Hisashi"}],"nameIdentifiers":[{"nameIdentifier":"634149","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Sihver, Lembit"}],"nameIdentifiers":[{"nameIdentifier":"634150","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Ｐｌｏｃ Ｏｎｄｒｅｊ","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"634151","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"内堀 幸夫","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"634152","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"北村 尚","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"634153","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Ｓｉｈｖｅｒ Ｌｅｍｂｉｔ","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"634154","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":"PHITS calculation of radiation field in HIMAC BIO","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"PHITS calculation of radiation field in HIMAC BIO"}]},"item_type_id":"10005","owner":"1","path":["29"],"pubdate":{"attribute_name":"公開日","attribute_value":"2011-09-13"},"publish_date":"2011-09-13","publish_status":"0","recid":"64309","relation_version_is_last":true,"title":["PHITS calculation of radiation field in HIMAC BIO"],"weko_creator_id":"1","weko_shared_id":-1},"updated":"2023-05-15T21:13:04.861987+00:00"}
