The S-LSR storage ring has a high super periodicity of 6 preferable from the beam dynamical point of view. Following the realization of one dimensional (1D) ordering of a 7 MeV proton beam, three dimensional (3D) laser cooling has been experimentally demonstrated for ions with non-negligible velocity (v/c=0.0019, c: light velocity). So as to suppress heating effects due to intra-beam scattering (IBS), the circulating ion beam intensity has been reduced by scraping and the normalized emittances: EPSn of 1.3×10-11 πm·rad and 8.5×10-12 πm·rad, corresponding to 6.4 K and 2.1 K, have been realized for the horizontal and vertical directions, respectively with a beam intensity of ~104 , which are the lowest temperatures ever attained by laser cooling. Molecular Dynamics (MD) computer simulation predicts the realization of the lowest beam temperatures of ~0.001 K and ~0.1 K corresponding to EPSn of the order of 10-13πm·rad and 10-12 πm·rad for the longitudinal and transverse directions, respectively. With the same condition as utilized for the real experiments at S-LSR, formation of a 1D longitudinal string is expected if the laser spot size and laser detuning are adjusted to the proper values of 1.5 mm and -42 MHz, respectively with ramping of the detuning. 3D ordered state is also predicted for a coasting beam with laser cooling utilizing dispersive cooling.","subitem_description_type":"Abstract"}]},"item_10003_publisher_8":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"JACoW"}]},"item_10003_relation_10":{"attribute_name":"ISBN","attribute_value_mlt":[{"subitem_relation_type_id":{"subitem_relation_type_id_text":"978-3-95450-132-8","subitem_relation_type_select":"ISBN"}}]},"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":"Noda, Akira"}],"nameIdentifiers":[{"nameIdentifier":"557501","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Nakao, Masao"}],"nameIdentifiers":[{"nameIdentifier":"557502","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"al., et"}],"nameIdentifiers":[{"nameIdentifier":"557503","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"野田 章","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"557504","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"中尾 政夫","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"557505","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 paper","resourceuri":"http://purl.org/coar/resource_type/c_5794"}]},"item_title":"Ultralow emittance beam production based on doppler laser cooling and coupling resonance","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"Ultralow emittance beam production based on doppler laser cooling and coupling resonance"}]},"item_type_id":"10003","owner":"1","path":["2"],"pubdate":{"attribute_name":"公開日","attribute_value":"2015-07-22"},"publish_date":"2015-07-22","publish_status":"0","recid":"54573","relation_version_is_last":true,"title":["Ultralow emittance beam production based on doppler laser cooling and coupling resonance"],"weko_creator_id":"1","weko_shared_id":-1},"updated":"2023-05-15T22:59:18.305206+00:00"}
