Previous models for flux enhancement of the radiation belt have assumed the stochastic process as a diffusion manner of successive random-phase interactions, but physical mechanisms for the acceleration are not fully incorporated in these models because of the lack of a nonlinear scattering process. Here we report rapid increase in relativistic electron flux by using an innovative computer simulation model that incorporates not only diffusive process but also nonlinear scattering processes. The simulations show that three types of scattering simultaneously occur, which are diffusive, phase trapping, and phase bunching. It is found that the phase trapping is the most efficient mechanism to produce the MeV electrons rapidly in the scattering processes. The electrons are accelerated from 400 keV to over 1 MeV in time scale less than 60 s. On the other hand, as the phase trapping is suppressed by the breaking of relative phase angle between waves and gyrating electrons during the interaction, the increase of electron flux at MeV energy is clearly reduced. Our simulations conclude that the phase-trapping process causes a significant effect for the increase in relativistic electron flux and suggest that a quasi-linear diffusion model is not always valid to fully describe the relativistic electron acceleration.", "subitem_description_language": "en", "subitem_description_type": "Abstract"}]}, "item_10_identifier_60": {"attribute_name": "URI", "attribute_value_mlt": [{"subitem_identifier_type": "DOI", "subitem_identifier_uri": "http://doi.org/10.1002/2016JA022696"}, {"subitem_identifier_type": "HDL", "subitem_identifier_uri": "http://hdl.handle.net/2237/25181"}]}, "item_10_publisher_32": {"attribute_name": "出版者", "attribute_value_mlt": [{"subitem_publisher": "Wiley", "subitem_publisher_language": "en"}]}, "item_10_relation_11": {"attribute_name": "DOI", "attribute_value_mlt": [{"subitem_relation_type": "isVersionOf", "subitem_relation_type_id": {"subitem_relation_type_id_text": "https://doi.org/10.1002/2016JA022696", "subitem_relation_type_select": "DOI"}}]}, "item_10_rights_12": {"attribute_name": "権利", "attribute_value_mlt": [{"subitem_rights": "© 2016 American Geophysical Union", "subitem_rights_language": "en"}]}, "item_10_select_15": {"attribute_name": "著者版フラグ", "attribute_value_mlt": [{"subitem_select_item": "publisher"}]}, "item_10_source_id_7": {"attribute_name": "ISSN", "attribute_value_mlt": [{"subitem_source_identifier": "2169-9356", "subitem_source_identifier_type": "EISSN"}]}, "item_1615787544753": {"attribute_name": "出版タイプ", "attribute_value_mlt": [{"subitem_version_resource": "http://purl.org/coar/version/c_970fb48d4fbd8a85", "subitem_version_type": "VoR"}]}, "item_access_right": {"attribute_name": "アクセス権", "attribute_value_mlt": [{"subitem_access_right": "open access", "subitem_access_right_uri": "http://purl.org/coar/access_right/c_abf2"}]}, "item_creator": {"attribute_name": "著者", "attribute_type": "creator", "attribute_value_mlt": [{"creatorNames": [{"creatorName": "Saito, Shinji", "creatorNameLang": "en"}], "nameIdentifiers": [{"nameIdentifier": "67954", "nameIdentifierScheme": "WEKO"}]}, {"creatorNames": [{"creatorName": "Miyoshi, Yoshizumi", "creatorNameLang": "en"}], "nameIdentifiers": [{"nameIdentifier": "67955", "nameIdentifierScheme": "WEKO"}]}, {"creatorNames": [{"creatorName": "Seki, Kanako", "creatorNameLang": "en"}], "nameIdentifiers": [{"nameIdentifier": "67956", "nameIdentifierScheme": "WEKO"}]}]}, "item_files": {"attribute_name": "ファイル情報", "attribute_type": "file", "attribute_value_mlt": [{"accessrole": "open_date", "date": [{"dateType": "Available", "dateValue": "2017-01-23"}], "displaytype": "detail", "download_preview_message": "", "file_order": 0, "filename": "Saito_et_al-2016-Journal_of_Geophysical_Research_Space_Physics.pdf", "filesize": [{"value": "8.4 MB"}], "format": "application/pdf", "future_date_message": "", "is_thumbnail": false, "licensetype": "license_note", "mimetype": "application/pdf", "size": 8400000.0, "url": {"label": "Saito_et_al-2016-Journal_of_Geophysical_Research_Space_Physics.pdf ファイル公開：2017/01/23", "objectType": "fulltext", "url": "https://nagoya.repo.nii.ac.jp/record/22997/files/Saito_et_al-2016-Journal_of_Geophysical_Research_Space_Physics.pdf"}, "version_id": "4ebed476-dc78-4d4a-8588-78224bff932f"}]}, "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": "Rapid increase in relativistic electron flux controlled by nonlinear phase trapping of whistler chorus elements", "item_titles": {"attribute_name": "タイトル", "attribute_value_mlt": [{"subitem_title": "Rapid increase in relativistic electron flux controlled by nonlinear phase trapping of whistler chorus elements", "subitem_title_language": "en"}]}, "item_type_id": "10", "owner": "1", "path": ["696"], "permalink_uri": "http://hdl.handle.net/2237/25181", "pubdate": {"attribute_name": "PubDate", "attribute_value": "2016-12-12"}, "publish_date": "2016-12-12", "publish_status": "0", "recid": "22997", "relation": {}, "relation_version_is_last": true, "title": ["Rapid increase in relativistic electron flux controlled by nonlinear phase trapping of whistler chorus elements"], "weko_shared_id": -1}
