Ahter annealing, the electrode was kept in 2 atm deuterium gas for 24 hours to be loading palladium. The deuterion to palladium loading ratio was measured to be about 0.6 at 24 hours after the start of loading. Next, the palladium electrode was set in atest cell, counter plane electrode was the bottom of the test cell with gap spacing of 10 mm. A DC high voltage of positive 4-8 keV was applied to the point electrode to form glow discharge condition. Measurment of excess neutron and gamma-ray started just after the voltage application. Each run continued for 24-l00 hours. The total number of runs was 59.\n\nNon of excess neutron and gamma-ray was observed during any run. After, each run, the surface of palladium electrode was investigated by XPS and EDX.The XPS and EDX revealed that considerable area was covered with iron, manganese, copper and silver. Similar run was performed at out-door, where background neutron was expected to be higher level. Iron and scandium were detected in 3 runs out of total 13 runs by XPS.\n\nAnother experiment under 3 Torr deuterium gas with rod-plane electrode was performed. A deuterium loaded round plladium disc of 0.3 mm thick and 10 mm diameter was set on the plane chatode. Anomalous peak clearly deferent from background was observed in gamma-ray spectrum in 10 runs out of total 28 runs.the peak corresponds to 106 keV in the energy spectrum. A kind of nuclear reaction seemed to occur in or on the palladium electrode during transfer of deuteron through the palladium under DC glow dischage condition. Iron was also detected by XPS on the palladium with the anomalous emission.","subitem_description_type":"Other"}]},"item_28_full_name_3":{"attribute_name":"著者別名","attribute_value_mlt":[{"nameIdentifiers":[{}],"names":[{"name":"YAMADA, Hiroshi"}]}]},"item_28_text_4":{"attribute_name":"著者(機関)","attribute_value_mlt":[{"subitem_text_value":"岩手大学工学部"}]},"item_28_version_type_27":{"attribute_name":"著者版フラグ","attribute_value_mlt":[{"subitem_version_resource":"http://purl.org/coar/version/c_ab4af688f83e57aa","subitem_version_type":"AM"}]},"item_creator":{"attribute_name":"著者","attribute_type":"creator","attribute_value_mlt":[{"creatorNames":[{"creatorName":"山田, 弘"}],"nameIdentifiers":[{}]}]},"item_files":{"attribute_name":"ファイル情報","attribute_type":"file","attribute_value_mlt":[{"accessrole":"open_date","date":[{"dateType":"Available","dateValue":"2016-11-14"}],"displaytype":"detail","filename":"kaken08650325.pdf","filesize":[{"value":"1.8 MB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"kaken08650325.pdf","url":"https://iwate-u.repo.nii.ac.jp/record/9661/files/kaken08650325.pdf"},"version_id":"cdc2b12f-2511-437e-bdf5-575f704776b9"}]},"item_keyword":{"attribute_name":"キーワード","attribute_value_mlt":[{"subitem_subject":"Charged particle","subitem_subject_scheme":"Other"},{"subitem_subject":"Current fluctuation","subitem_subject_scheme":"Other"},{"subitem_subject":"Deuterium","subitem_subject_scheme":"Other"},{"subitem_subject":"Excess heat","subitem_subject_scheme":"Other"},{"subitem_subject":"High voltage application","subitem_subject_scheme":"Other"},{"subitem_subject":"Hydrogen loading","subitem_subject_scheme":"Other"},{"subitem_subject":"Neutron","subitem_subject_scheme":"Other"},{"subitem_subject":"Palladium","subitem_subject_scheme":"Other"},{"subitem_subject":"パラジウム","subitem_subject_scheme":"Other"},{"subitem_subject":"中性子","subitem_subject_scheme":"Other"},{"subitem_subject":"余剰熱","subitem_subject_scheme":"Other"},{"subitem_subject":"水素吸蔵","subitem_subject_scheme":"Other"},{"subitem_subject":"荷電粒子","subitem_subject_scheme":"Other"},{"subitem_subject":"重水素","subitem_subject_scheme":"Other"},{"subitem_subject":"電流変動","subitem_subject_scheme":"Other"},{"subitem_subject":"高電界印加","subitem_subject_scheme":"Other"}]},"item_language":{"attribute_name":"言語","attribute_value_mlt":[{"subitem_language":"jpn"}]},"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":"加圧ガス中グロー放電を用いた重水素吸蔵固体中の過剰熱発生に関する研究","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"加圧ガス中グロー放電を用いた重水素吸蔵固体中の過剰熱発生に関する研究"}]},"item_type_id":"28","owner":"3","path":["1516"],"pubdate":{"attribute_name":"公開日","attribute_value":"2012-02-08"},"publish_date":"2012-02-08","publish_status":"0","recid":"9661","relation_version_is_last":true,"title":["加圧ガス中グロー放電を用いた重水素吸蔵固体中の過剰熱発生に関する研究"],"weko_creator_id":"3","weko_shared_id":-1},"updated":"2023-05-16T11:00:31.824010+00:00"}
