But fast neutron responses of the neutron senseors have never been resolved, yet. It is because energy deposition in partial-depletion silicon sensors is different with that in original depletion layer. To resolve this difference, we found funneling effect in the silicon sensor [1]. The funneling effect enlarges depths of energy deposition in partial-depletion silicon sensor by transmitted charged particles through the sensors. Now, we developed new response of energy deposition in the silicon sensors by considering this funneling effect and improved funneling effect as a function of incident particle energy, which were experimentally evaluated by measuring proton beams directly at the NIRS cyclotron facility in Japan. Based on these mechanisms of charged-particle energy deposition we simulate fast-neutron response functions of the neutron silicon sensors, and compare with experimental neutron response functions. The experimental response functions for 5 and 15 MeV mono-energy neutrons were obtained using standard fast neutron beams in NMIJ-AIST in Japan. The neutron fluxes have been provided with high accuracy within a few %, and have been internationally calibrated with several institutes. The measured and simulated response functions for 15 MeV mono-energy neutrons are plotted in below figure. Original mechanism of energy deposition in silicon sensor cannot simulate the neutron responses, however, our developed model including the funneling effect can simulate the neutron responses well. Based on our method, we can evaluate dosimeter response functions for higher neutron energy and any irradiation geometries. Our model is useful to develop neutron dosimeters.","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":"Sixth International Symposium on Radiation Safety and Detection Technology(ISORD-6)","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":"Takada, Masashi"}],"nameIdentifiers":[{"nameIdentifier":"633851","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"高田 真志","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"633852","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":"Neutron Response Functions of Silicon-based Real-time Personal Neutron Dosimeter: Experiments and Simulations","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"Neutron Response Functions of Silicon-based Real-time Personal Neutron Dosimeter: Experiments and Simulations"}]},"item_type_id":"10005","owner":"1","path":["29"],"pubdate":{"attribute_name":"公開日","attribute_value":"2011-07-20"},"publish_date":"2011-07-20","publish_status":"0","recid":"64271","relation_version_is_last":true,"title":["Neutron Response Functions of Silicon-based Real-time Personal Neutron Dosimeter: Experiments and Simulations"],"weko_creator_id":"1","weko_shared_id":-1},"updated":"2023-05-15T21:13:31.472560+00:00"}
