A misalignment could occur between the divertor cassette and measurement system. It is shown that the misalignment can be compensated to some extent by rotating the first mirror. The maximum compensable misalignment and the required accuracy in the alignment are discussed. It is likely that the surface roughness of the first mirrors gradually increases during ITER operation. We investigated the required quality of the first mirror as focusing on the beam divergence using the ray tracing model. Moreover, to check the performance, helium plasma irradiation was performed on molybdenum mirror samples, and the beam divergence was measured using a laser and a detector. Based on the simulations and experiments, it is shown that the helium effect does not harm the performance of the mirror when the mirror temperature is less than 800 K.","subitem_description_type":"Abstract"}]},"item_8_publisher_8":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"IOP Publishing"}]},"item_8_relation_14":{"attribute_name":"DOI","attribute_value_mlt":[{"subitem_relation_type_id":{"subitem_relation_type_id_text":"10.1088/1748-0221/15/11/P11035","subitem_relation_type_select":"DOI"}}]},"item_8_relation_17":{"attribute_name":"関連サイト","attribute_value_mlt":[{"subitem_relation_type_id":{"subitem_relation_type_id_text":"https://iopscience.iop.org/article/10.1088/1748-0221/15/11/P11035","subitem_relation_type_select":"URI"}}]},"item_8_source_id_9":{"attribute_name":"ISSN","attribute_value_mlt":[{"subitem_source_identifier":"1748-0221","subitem_source_identifier_type":"ISSN"}]},"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":"Kajita, S."}],"nameIdentifiers":[{"nameIdentifier":"1012441","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Hiroaki, Ogawa"}],"nameIdentifiers":[{"nameIdentifier":"1012442","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Kitazawa, Sin-iti"}],"nameIdentifiers":[{"nameIdentifier":"1012443","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Toshihiro, Oikawa"}],"nameIdentifiers":[{"nameIdentifier":"1012444","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Veshchev, E."}],"nameIdentifiers":[{"nameIdentifier":"1012445","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Hiroaki, Ogawa","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"1012446","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Kitazawa, Sin-iti","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"1012447","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Toshihiro, Oikawa","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"1012448","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":"journal article","resourceuri":"http://purl.org/coar/resource_type/c_6501"}]},"item_title":"Performance of first mirrors for divertor impurity monitor in ITER: compensation of misalignment and effect of beam divergence","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"Performance of first mirrors for divertor impurity monitor in ITER: compensation of misalignment and effect of beam divergence"}]},"item_type_id":"8","owner":"1","path":["1"],"pubdate":{"attribute_name":"公開日","attribute_value":"2021-02-17"},"publish_date":"2021-02-17","publish_status":"0","recid":"81854","relation_version_is_last":true,"title":["Performance of first mirrors for divertor impurity monitor in ITER: compensation of misalignment and effect of beam divergence"],"weko_creator_id":"1","weko_shared_id":-1},"updated":"2023-05-15T18:55:58.151355+00:00"}
