Various operating parameters including mercury flow rate, keeper current, collector voltage and collector distance were employed. Several open type hollow cathodes with different orifice diameters were tested in order to determine the scale effect. Hollow cathodes were operated in both spot and plume modes, in order to obtain different kinds of voltage-current characteristics. Transition from one mode to the other at a constant mercury flow rate was attained by varying the keeper current across a specific current level. The scale effect of orifice diameter indicated that at the mode transition point, the collector current was a specific function of the number density of the mercury vapor in or near the cathode orifice. The increase in cathode heater current caused an increase in collector current in the spot mode, while a decrease in the plume mode as the difference between the modes. An enclosed type cathode was also tested and proved that it had the advantage of low keeper voltage and current compared with the open type.","subitem_description_type":"Other"}]},"item_3_description_32":{"attribute_name":"資料番号","attribute_value_mlt":[{"subitem_description":"資料番号: NALTR0475000","subitem_description_type":"Other"}]},"item_3_description_33":{"attribute_name":"レポート番号","attribute_value_mlt":[{"subitem_description":"レポート番号: NAL TR-475","subitem_description_type":"Other"}]},"item_3_publisher_8":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"航空宇宙技術研究所"}]},"item_3_publisher_9":{"attribute_name":"出版者（英）","attribute_value_mlt":[{"subitem_publisher":"National Aerospace Laboratory(NAL)"}]},"item_3_source_id_21":{"attribute_name":"ISSN","attribute_value_mlt":[{"subitem_source_identifier":"0389-4010","subitem_source_identifier_type":"ISSN"}]},"item_3_text_6":{"attribute_name":"著者所属","attribute_value_mlt":[{"subitem_text_value":"航空宇宙技術研究所宇宙研究グループ"}]},"item_3_text_7":{"attribute_name":"著者所属（英）","attribute_value_mlt":[{"subitem_text_language":"en","subitem_text_value":"Space Technology Research Group, National Aerospace Laboratory(NAL)"}]},"item_creator":{"attribute_name":"著者","attribute_type":"creator","attribute_value_mlt":[{"creatorNames":[{"creatorName":"東, 久雄"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"AZUMA, Hisao","creatorNameLang":"en"}],"nameIdentifiers":[{}]}]},"item_files":{"attribute_name":"ファイル情報","attribute_type":"file","attribute_value_mlt":[{"accessrole":"open_date","date":[{"dateType":"Available","dateValue":"2020-01-29"}],"displaytype":"detail","filename":"naltr00475.pdf","filesize":[{"value":"928.8 kB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"naltr00475.pdf","url":"https://jaxa.repo.nii.ac.jp/record/44728/files/naltr00475.pdf"},"version_id":"62d66ab6-c10f-4789-9bff-fc717f09e54d"}]},"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":"technical report","resourceuri":"http://purl.org/coar/resource_type/c_18gh"}]},"item_title":"ホローカソードの実験的研究(Ⅰ)","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"ホローカソードの実験的研究(Ⅰ)"}]},"item_type_id":"3","owner":"1","path":["1893","1917"],"pubdate":{"attribute_name":"公開日","attribute_value":"2015-03-26"},"publish_date":"2015-03-26","publish_status":"0","recid":"44728","relation_version_is_last":true,"title":["ホローカソードの実験的研究(Ⅰ)"],"weko_creator_id":"1","weko_shared_id":-1},"updated":"2023-06-20T21:51:52.450801+00:00"}
