In this method, photon flux is split into two wavelength ranges, one with large transmission losses and the other with small transmission losses. Each split photon flux is detected by a silicon photomultiplier. The position is detected by evaluating the degree of red-shift of the optical spectrum from the output signal ratio of the two silicon photomultipliers. A proof-of-principle experiment showed that the position of Sr90 beta radiation sources can be detected by proposed method. The proposed method uses coincidence measurements to improve the signal-to-noise ratio. It is clarify that the measurement result depends on the threshold value of the coincidence measurement and that the threshold value is an important parameter in the proposed measurement.","subitem_description_language":"en","subitem_description_type":"Abstract"},{"subitem_description":"研究分野：量子ビーム科学関連","subitem_description_language":"ja","subitem_description_type":"Other"}]},"item_30001_file22":{"attribute_name":"ファイル情報","attribute_type":"file","attribute_value_mlt":[{"accessrole":"open_access","filename":"20K12500seika.pdf","format":"application/pdf","mimetype":"application/pdf","url":{"url":"https://kindai.repo.nii.ac.jp/record/2000332/files/20K12500seika.pdf"},"version_id":"61b19567-57a1-412c-80e0-6210d4fe87cb"}]},"item_30001_funding_reference15":{"attribute_name":"助成情報","attribute_value_mlt":[{"subitem_award_numbers":{"subitem_award_number":"20K12500","subitem_award_uri":"https://kaken.nii.ac.jp/grant/KAKENHI-PROJECT-20K12500/"},"subitem_award_titles":[{"subitem_award_title":"光スペクトルの赤方偏移に基づく放射線検出技術","subitem_award_title_language":"ja"},{"subitem_award_title":"Radiation detection method based on the redshift of the optical spectrum","subitem_award_title_language":"en"}],"subitem_funder_names":[{"subitem_funder_name":"独立行政法人日本学術振興会","subitem_funder_name_language":"ja"},{"subitem_funder_name":"Japan Society for the Promotion of Science","subitem_funder_name_language":"en"}]}]},"item_30001_language10":{"attribute_name":"言語","attribute_value_mlt":[{"subitem_language":"jpn"}]},"item_30001_subject7":{"attribute_name":"キーワード","attribute_value_mlt":[{"subitem_subject":"放射線検出","subitem_subject_language":"ja","subitem_subject_scheme":"Other"},{"subitem_subject":"微弱光検出","subitem_subject_language":"ja","subitem_subject_scheme":"Other"},{"subitem_subject":"光スペクトルの赤方偏移","subitem_subject_language":"ja","subitem_subject_scheme":"Other"},{"subitem_subject":"位置検出器","subitem_subject_language":"ja","subitem_subject_scheme":"Other"}]},"item_30001_title0":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"光スペクトルの赤方偏移に基づく放射線検出技術","subitem_title_language":"ja"},{"subitem_title":"Radiation detection method based on the redshift of the optical spectrum","subitem_title_language":"en"}]},"item_30001_version_type12":{"attribute_name":"出版タイプ","attribute_value_mlt":[{"subitem_version_resource":"http://purl.org/coar/version/c_970fb48d4fbd8a85","subitem_version_type":"VoR"}]},"item_title":"光スペクトルの赤方偏移に基づく放射線検出技術","item_type_id":"40001","owner":"42","path":["1697004343623"],"pubdate":{"attribute_name":"PubDate","attribute_value":"2023-11-08"},"publish_date":"2023-11-08","publish_status":"0","recid":"2000332","relation_version_is_last":true,"title":["光スペクトルの赤方偏移に基づく放射線検出技術"],"weko_creator_id":"42","weko_shared_id":-1},"updated":"2024-02-09T05:13:32.882464+00:00"}
