One is an in-situ pipe-gun type pellet injector, which has the simplest design of all pellet injectors. This in-situ pipe-gun injector has 10 injection barrels, each of which can independently inject cylindrical solid hydrogen pellets (3.4 and 3.8mm in diameter and length, respectively) at velocities up to 1,200m/s. The other is a repetitive pellet injector with a screw extruder, which can form a 3.0mmφ solid hydrogen rod continuously at extrusion rates up to 55mm/s. This extruder allows consecutive pellet injection up to 11Hz without time limit. Both of these pellet injectors employ compact cryo-coolers to solidify hydrogen; therefore, they can be operated using only electrical input instead of a complicated liquid helium\nsupply system. In particular, using a combination of the repetitive pellet injector with cryo-coolers provides a steady-state capability with minimum maintenance.","subitem_description_type":"Abstract"}]},"item_2_publisher_8":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"プラズマ・核融合学会"}]},"item_2_relation_14":{"attribute_name":"DOI","attribute_value_mlt":[{"subitem_relation_type_id":{"subitem_relation_type_id_text":"10.1585/pfr.4.002","subitem_relation_type_select":"DOI"}}]},"item_2_rights_15":{"attribute_name":"権利","attribute_value_mlt":[{"subitem_rights":"? 2009 The Japan Society of Plasma Science and Nuclear Fusion Research"}]},"item_creator":{"attribute_name":"著者","attribute_type":"creator","attribute_value_mlt":[{"creatorNames":[{"creatorName":"SAKAMOTO,  Ryuichi","creatorNameLang":"en"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"YAMADA,  Hiroshi","creatorNameLang":"en"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"LHD, experimental group","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":"2016-03-11"}],"displaytype":"detail","filename":"pfr2009_04-002.pdf","filesize":[{"value":"1.3 MB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"pfr2009_04-002.pdf","url":"https://nifs-repository.repo.nii.ac.jp/record/211/files/pfr2009_04-002.pdf"},"version_id":"efa7fe1b-f508-42f6-9d4b-a3f7521c5e26"}]},"item_keyword":{"attribute_name":"キーワード","attribute_value_mlt":[{"subitem_subject":"solid hydrogen pellet","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"fueling","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"cryo-cooler","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"pellet injector","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"steady state operation","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":"journal article","resourceuri":"http://purl.org/coar/resource_type/c_6501"}]},"item_title":"Development of Advanced Pellet Injector Systems for Plasma Fueling","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"Development of Advanced Pellet Injector Systems for Plasma Fueling","subitem_title_language":"en"}]},"item_type_id":"2","owner":"3","path":["7"],"pubdate":{"attribute_name":"公開日","attribute_value":"2011-04-05"},"publish_date":"2011-04-05","publish_status":"0","recid":"211","relation_version_is_last":true,"title":["Development of Advanced Pellet Injector Systems for Plasma Fueling"],"weko_creator_id":"3","weko_shared_id":-1},"updated":"2023-06-20T20:47:32.151951+00:00"}
