From June 2017, we started operation with accelerating voltage 500 kV with electron\ngun test mode operation, then 500 keV beam was supplied in cERL operation in March and June 2018. As a result,\nwe succeeded in maintaining the acceleration voltage of 500 kV without causing discharge even for 369 hours or more.\nFrom the experience of the operation of the electron gun there is a possibility that a very slow conditioning effect may\nbe obtained even during high voltage operation. It is presumed that stable operation itself contributes to making a state\nwhere discharge is less likely to occur. We report on the background and current problems that the state of acceleration\nDC voltage of 500 kV can be maintained for a long time stably","subitem_description_type":"Abstract"}]},"item_10003_relation_17":{"attribute_name":"関連サイト","attribute_value_mlt":[{"subitem_relation_name":[{"subitem_relation_name_text":"https://www.pasj.jp/web_publish/pasj2018/proceedings/PDF/FROM/FROM03.pdf"}],"subitem_relation_type_id":{"subitem_relation_type_id_text":"https://www.pasj.jp/web_publish/pasj2018/proceedings/PDF/FROM/FROM03.pdf","subitem_relation_type_select":"URI"}}]},"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":"山本将博"}],"nameIdentifiers":[{"nameIdentifier":"561925","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"西森, 信行"}],"nameIdentifiers":[{"nameIdentifier":"561926","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"宮島司"}],"nameIdentifiers":[{"nameIdentifier":"561927","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"本田洋介"}],"nameIdentifiers":[{"nameIdentifier":"561928","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"羽島, 良一"}],"nameIdentifiers":[{"nameIdentifier":"561929","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"西森 信行","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"561930","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"羽島 良一","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"561931","nameIdentifierScheme":"WEKO"}]}]},"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":"conference paper","resourceuri":"http://purl.org/coar/resource_type/c_5794"}]},"item_title":"compact-ERL DC電子銃の500 kV長期安定運転","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"compact-ERL DC電子銃の500 kV長期安定運転"}]},"item_type_id":"10003","owner":"1","path":["2"],"pubdate":{"attribute_name":"公開日","attribute_value":"2019-01-10"},"publish_date":"2019-01-10","publish_status":"0","recid":"54951","relation_version_is_last":true,"title":["compact-ERL DC電子銃の500 kV長期安定運転"],"weko_creator_id":"1","weko_shared_id":-1},"updated":"2023-05-15T22:55:02.975752+00:00"}
