The system consists of a small vessel (30 ml) to reserve CH4-gas, and two fast solenoid valves that are installed at both sides of the vessel. They are connected to each other and to the Kei2-source by using a stainless-steel pipe (4 mm in inner-diameter), where the length of the pipe from the valve to the source is 60 cm and the conductance is 1.2 l/s.\nFrom the results of a test, almost 300 eA for a pulsed 12C4+ beam was obtained at a Faraday-cup in an extraction-beam channel with a pressure range of 4000 Pa in the vessel. At this time, the valve has an open time of 10 ms and the delay time between the valve-open and applying microwave power is 100 ms, respectively.\nIn experiments, the conversion efficiency for input CH4 molecules to the quantity of extracted 12C4+ ions in one beam-pulse was found to be around 3%, and the ratio of the total amount of the gas requirement was only 10% compared with a case of continuous gas provided in 3.3 second of repetition in HIMAC.","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":"第12回イオン源国際会議","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":"Houjou, Satoru"}],"nameIdentifiers":[{"nameIdentifier":"677987","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"北條 悟","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"677988","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":"Application of compact ECR ion source","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"Application of compact ECR ion source"}]},"item_type_id":"10005","owner":"1","path":["28"],"pubdate":{"attribute_name":"公開日","attribute_value":"2007-09-05"},"publish_date":"2007-09-05","publish_status":"0","recid":"69087","relation_version_is_last":true,"title":["Application of compact ECR ion source"],"weko_creator_id":"1","weko_shared_id":-1},"updated":"2023-05-15T20:18:38.682260+00:00"}
