This spectrometer has such advantages as: 1. direct measurement of the neutron energy without the unfolding procedure, 2. relatively high detection efficiency for 14 MeV neutrons, 3. a wide dynamic range of counting rate, and 4. perfect n-gamma discrimination. To examine the performance of this spectrometer, we developed a Monte Carlo simulation code. It predicts that we may achieve energy resolution up to 3% with a detection efficiency of 10^-5 [count cm^2/n] if we could successfully adjust the condition of the spectrometer. A prototype spectrometer was constructed and was compared with the Monte Carlo prediction. The energy resolution of 5.3 pm 0.7% for 14 MeV neutron was obtained for the prototype spectrometer and the calculation agrees with the experimental results within its margin of error if we take into account the intrinsic energy resolution of the detector that is used in the prototype.\"","subitem_description_type":"Abstract"}]},"item_5_source_id_10":{"attribute_name":"ISSN","attribute_value_mlt":[{"subitem_source_identifier":"0915-633X","subitem_source_identifier_type":"ISSN"}]},"item_5_text_8":{"attribute_name":"報告書番号","attribute_value_mlt":[{"subitem_text_value":"NIFS-205"}]},"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":"\"Osakabe,  M.","creatorNameLang":"en"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"Itoh,  S.","creatorNameLang":"en"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"Gotoh,  Y.","creatorNameLang":"en"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"Sasao,  M.","creatorNameLang":"en"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"Fujita,  J.\"","creatorNameLang":"en"}],"nameIdentifiers":[{}]}]},"item_keyword":{"attribute_name":"キーワード","attribute_value_mlt":[{"subitem_subject":"DT neutron","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"neutron energy spectrum","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"neutron spectrometer","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"recoil proton telescoope","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"plastic scintillator","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"plasma diagnosrics","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"neutron diagnostics","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"ion temperature","subitem_subject_language":"en","subitem_subject_scheme":"Other"}]},"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":"research report","resourceuri":"http://purl.org/coar/resource_type/c_18ws"}]},"item_title":"A Compact Neutron Counter Telescope with Thick Radiator (Cotetra) for Fusion Experiment","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"A Compact Neutron Counter Telescope with Thick Radiator (Cotetra) for Fusion Experiment","subitem_title_language":"en"}]},"item_type_id":"5","owner":"3","path":["32"],"pubdate":{"attribute_name":"公開日","attribute_value":"2010-02-05"},"publish_date":"2010-02-05","publish_status":"0","recid":"10134","relation_version_is_last":true,"title":["A Compact Neutron Counter Telescope with Thick Radiator (Cotetra) for Fusion Experiment"],"weko_creator_id":"3","weko_shared_id":-1},"updated":"2023-06-20T20:53:13.855765+00:00"}
