This IEC device is configured from a titanium anode and a\nmolybdenum cathode with diameters of 17 and 6 cm, respectively. A high-intensity neutron source operated in a\nstable pulse shape is mandatory to increase the system’s reliability. Applying a higher voltage is a straightforward\nway to increase the neutron yield from the system. However, a contradiction between the increase of the\napplied voltage and the reduction of the system size limits such a proposal. A three-stage feedthrough system is\nemployed in the developed compact IEC to address this contradiction. A feedback control system was developed\nand applied to the input and output parameters, such as the applied voltage and the neutron yield, to increase its\nstability in long-term operation. Characterization of the developed system was performed by scanning the\nneutron yield as a function of applied voltage and cathode current. To date, a maximum neutron yield of 9.2 ×\n107n⋅s–1 at 6.4 kW (80 kV and 80 mA) has been obtained. A study of the feasibility of using the IEC system for\nneutron radiography was performed. Preliminary analysis of the resulting images showed there was good\ncontrast between the sample and the background. The results suggest that optimization of the experimental\nparameters is needed to perform higher accuracy neutron radiography.","subitem_description_type":"Abstract"}]},"item_8_publisher_8":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"Elsevier"}]},"item_8_relation_14":{"attribute_name":"DOI","attribute_value_mlt":[{"subitem_relation_type_id":{"subitem_relation_type_id_text":"10.1016/j.fusengdes.2021.112346","subitem_relation_type_select":"DOI"}}]},"item_8_relation_17":{"attribute_name":"関連サイト","attribute_value_mlt":[{"subitem_relation_type_id":{"subitem_relation_type_id_text":"https://doi.org/10.1016/j.fusengdes.2021.112346","subitem_relation_type_select":"DOI"}}]},"item_8_source_id_9":{"attribute_name":"ISSN","attribute_value_mlt":[{"subitem_source_identifier":"0920-3796","subitem_source_identifier_type":"ISSN"}]},"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":"Bakr, Mahmoud"}],"nameIdentifiers":[{"nameIdentifier":"1010204","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Mukai, Keisuke"}],"nameIdentifiers":[{"nameIdentifier":"1010205","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Kai, Masuda"}],"nameIdentifiers":[{"nameIdentifier":"1010206","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Yagi, Juro"}],"nameIdentifiers":[{"nameIdentifier":"1010207","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Konishi, Satoshi"}],"nameIdentifiers":[{"nameIdentifier":"1010208","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Kai, Masuda","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"1010209","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":"journal article","resourceuri":"http://purl.org/coar/resource_type/c_6501"}]},"item_title":"Characterization of an ultra-compact neutron source based on an IEC fusion device and its prospective applications in radiography","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"Characterization of an ultra-compact neutron source based on an IEC fusion device and its prospective applications in radiography"}]},"item_type_id":"8","owner":"1","path":["1"],"pubdate":{"attribute_name":"公開日","attribute_value":"2021-02-25"},"publish_date":"2021-02-25","publish_status":"0","recid":"81995","relation_version_is_last":true,"title":["Characterization of an ultra-compact neutron source based on an IEC fusion device and its prospective applications in radiography"],"weko_creator_id":"1","weko_shared_id":-1},"updated":"2023-05-15T19:04:56.531912+00:00"}
