Initially, we observe excitation of the right-hand polarized waves propagating parallel to the field-aligned ion beam, which is given as the free energy source. In the nonlinear stage, we observed the phase space bunching of beam ions by the excited waves. We apply this bunching effect to the explanation of 'gyrophased bunched' ions observed in the foreshock region.","subitem_description_type":"Other"}]},"item_1_source_id_13":{"attribute_name":"雑誌書誌ID","attribute_value_mlt":[{"subitem_source_identifier":"AA00733561","subitem_source_identifier_type":"NCID"}]},"item_1_text_10":{"attribute_name":"著者所属(英)","attribute_value_mlt":[{"subitem_text_language":"en","subitem_text_value":"Institute of Space and Astronautical Science/Institute of Space and Astronautical Science"}]},"item_files":{"attribute_name":"ファイル情報","attribute_type":"file","attribute_value_mlt":[{"accessrole":"open_date","date":[{"dateType":"Available","dateValue":"1985-07-01"}],"displaytype":"detail","filename":"KJ00000012401.pdf","filesize":[{"value":"2.1 MB"}],"format":"application/pdf","licensetype":"license_6","mimetype":"application/pdf","url":{"label":"KJ00000012401","url":"https://nipr.repo.nii.ac.jp/record/1769/files/KJ00000012401.pdf"},"version_id":"77da1cce-6ea8-470b-a9a3-66c33cf5a549"}]},"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":"departmental bulletin paper","resourceuri":"http://purl.org/coar/resource_type/c_6501"}]},"item_title":"Numerical study of the upstream wave excitation mechanism: 1.
