During cool down, nominal operation and\nwarm-up the thermal shields, the superconducting magnets and their structures, the high temperature\nsuperconductor current leads (HTS CL) and the divertor cryo pumps have to be supplied with helium\nat specific flow rates, pressures and temperatures. The monitoring of temperatures, mass flows, and\npressures and the control of the helium flows is performed by a Magnet Controller (MC).\nA particular abnormal situation is a quench or a fast discharge of a magnet which would\nrequire many hours for recovery to normal operation. In order to avoid fast discharges as far as possible,\nthe MC uses “safety interlocks” to supervise the magnet coils and the HTS CL. These interlocks react\non deviations of temperatures, pressures or mass flow rates from their nominal values and initiate\nappropriate counteractions. If a state reaches a critical threshold, a normal stop (NS) of a magnet is\ninitiated through the “Supervisory Control System and Data Acquisition System” (SCSDAS) by\nramping-down the current in the coils. In case of a fast discharge the MC acts directly on the power\nsupplies with parallel information to the SCSDAS.\nThe thresholds are derived from simulations of the cryogenic loops using the thermal\nanalysis programs FLOWER, HEATER, and SUPERMAGNET.\nThe presentation will describe the philosophy and logic of the Magnet Controller and explain the\ncalculation of some thresholds.", "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": "30th Symposium on Fusion Technology (SOFT 2018)", "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": "福井, 良磨"}], "nameIdentifiers": [{"nameIdentifier": "717456", "nameIdentifierScheme": "WEKO"}]}, {"creatorNames": [{"creatorName": "神谷, 宏治"}], "nameIdentifiers": [{"nameIdentifier": "717457", "nameIdentifierScheme": "WEKO"}]}, {"creatorNames": [{"creatorName": "夏目, 恭平"}], "nameIdentifiers": [{"nameIdentifier": "717458", "nameIdentifierScheme": "WEKO"}]}, {"creatorNames": [{"creatorName": "木津, 要"}], "nameIdentifiers": [{"nameIdentifier": "717459", "nameIdentifierScheme": "WEKO"}]}, {"creatorNames": [{"creatorName": "河野, 勝己"}], "nameIdentifiers": [{"nameIdentifier": "717460", "nameIdentifierScheme": "WEKO"}]}, {"creatorNames": [{"creatorName": "礒野, 高明"}], "nameIdentifiers": [{"nameIdentifier": "717461", "nameIdentifierScheme": "WEKO"}]}, {"creatorNames": [{"creatorName": "村上, 陽之"}], "nameIdentifiers": [{"nameIdentifier": "717462", "nameIdentifierScheme": "WEKO"}]}, {"creatorNames": [{"creatorName": "土屋, 勝彦"}], "nameIdentifiers": [{"nameIdentifier": "717463", "nameIdentifierScheme": "WEKO"}]}, {"creatorNames": [{"creatorName": "Heller, (Karlsruhe Institute of Technology) Reinhard"}], "nameIdentifiers": [{"nameIdentifier": "717464", "nameIdentifierScheme": "WEKO"}]}, {"creatorNames": [{"creatorName": "福井 良磨", "creatorNameLang": "en"}], "nameIdentifiers": [{"nameIdentifier": "717465", "nameIdentifierScheme": "WEKO"}]}, {"creatorNames": [{"creatorName": "神谷 宏治", "creatorNameLang": "en"}], "nameIdentifiers": [{"nameIdentifier": "717466", "nameIdentifierScheme": "WEKO"}]}, {"creatorNames": [{"creatorName": "夏目 恭平", "creatorNameLang": "en"}], "nameIdentifiers": [{"nameIdentifier": "717467", "nameIdentifierScheme": "WEKO"}]}, {"creatorNames": [{"creatorName": "木津 要", "creatorNameLang": "en"}], "nameIdentifiers": [{"nameIdentifier": "717468", "nameIdentifierScheme": "WEKO"}]}, {"creatorNames": [{"creatorName": "河野 勝己", "creatorNameLang": "en"}], "nameIdentifiers": [{"nameIdentifier": "717469", "nameIdentifierScheme": "WEKO"}]}, {"creatorNames": [{"creatorName": "礒野 高明", "creatorNameLang": "en"}], "nameIdentifiers": [{"nameIdentifier": "717470", "nameIdentifierScheme": "WEKO"}]}, {"creatorNames": [{"creatorName": "村上 陽之", "creatorNameLang": "en"}], "nameIdentifiers": [{"nameIdentifier": "717471", "nameIdentifierScheme": "WEKO"}]}, {"creatorNames": [{"creatorName": "土屋 勝彦", "creatorNameLang": "en"}], "nameIdentifiers": [{"nameIdentifier": "717472", "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": "Monitoring and Control of the Magnet System of JT-60SA", "item_titles": {"attribute_name": "タイトル", "attribute_value_mlt": [{"subitem_title": "Monitoring and Control of the Magnet System of JT-60SA"}]}, "item_type_id": "10005", "owner": "1", "path": ["28"], "permalink_uri": "https://repo.qst.go.jp/records/72828", "pubdate": {"attribute_name": "公開日", "attribute_value": "2018-06-18"}, "publish_date": "2018-06-18", "publish_status": "0", "recid": "72828", "relation": {}, "relation_version_is_last": true, "title": ["Monitoring and Control of the Magnet System of JT-60SA"], "weko_shared_id": -1}
