The FFAG accelerator magnet is<br /> required to have a nonlinear magnetic field that increases with <i>k</i>-th power of<br /> the orbit radius, where <i>k</i> is the field index in the accelerator. The required<br /> nonlinear magnetic field has been investigated with combined function coils,<br /> which consist of a large elliptical aperture, designed by using a computer<br /> code that was specifically developed for this purpose. It has been under-<br />stood from tracking that the integrated magnetic field along the beam path<br /> is the important parameter to be optimized. The field quality was evaluated<br /> with a particle trajectory simulation in which a particle could circulate well<br /> with stable tune. A prototype coil has been successfully developed by using<br /> a 6-axis CNC winding machine. The magnetic field and cryogenic character-<br />istics of the prototype have been verified in warm and cold measurements.<br /> As a consequence, a superconducting combined function coil design has been<br /> made for future application in the FFAG accelerator, and its technical fea-<br />sibility has been verified with the prototype magnet development and the<br /> performance test.","subitem_description_type":"Other"}]},"item_1_description_7":{"attribute_name":"学位記番号","attribute_value_mlt":[{"subitem_description":"総研大甲第939号","subitem_description_type":"Other"}]},"item_1_select_14":{"attribute_name":"所蔵","attribute_value_mlt":[{"subitem_select_item":"有"}]},"item_1_select_8":{"attribute_name":"研究科","attribute_value_mlt":[{"subitem_select_item":"高エネルギー加速器科学研究科"}]},"item_1_select_9":{"attribute_name":"専攻","attribute_value_mlt":[{"subitem_select_item":"12 加速器科学専攻"}]},"item_1_text_10":{"attribute_name":"学位授与年度","attribute_value_mlt":[{"subitem_text_value":"2005"}]},"item_creator":{"attribute_name":"著者","attribute_type":"creator","attribute_value_mlt":[{"creatorNames":[{"creatorName":"OBANA, Tetsuhiro","creatorNameLang":"en"}],"nameIdentifiers":[{}]}]},"item_files":{"attribute_name":"ファイル情報","attribute_type":"file","attribute_value_mlt":[{"accessrole":"open_date","date":[{"dateType":"Available","dateValue":"2016-02-17"}],"displaytype":"simple","filename":"甲939_要旨.pdf","filesize":[{"value":"178.8 kB"}],"format":"application/pdf","licensetype":"license_11","mimetype":"application/pdf","url":{"label":"要旨・審査要旨","url":"https://ir.soken.ac.jp/record/634/files/甲939_要旨.pdf"},"version_id":"1ebc0b0d-291a-4035-b32e-7118ae320d13"},{"accessrole":"open_date","date":[{"dateType":"Available","dateValue":"2016-02-17"}],"displaytype":"simple","filename":"甲939_本文.pdf","filesize":[{"value":"16.2 MB"}],"format":"application/pdf","licensetype":"license_11","mimetype":"application/pdf","url":{"label":"本文","url":"https://ir.soken.ac.jp/record/634/files/甲939_本文.pdf"},"version_id":"9175d558-5323-4689-9148-df585de0d8d9"}]},"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":"thesis","resourceuri":"http://purl.org/coar/resource_type/c_46ec"}]},"item_title":"Study of Combined Function Superconducting Accelerator Magnets containing Higher Harmonics","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"Study of Combined Function Superconducting Accelerator Magnets containing Higher Harmonics"},{"subitem_title":"Study of Combined Function Superconducting Accelerator Magnets containing Higher Harmonics","subitem_title_language":"en"}]},"item_type_id":"1","owner":"1","path":["14"],"pubdate":{"attribute_name":"公開日","attribute_value":"2010-02-22"},"publish_date":"2010-02-22","publish_status":"0","recid":"634","relation_version_is_last":true,"title":["Study of Combined Function Superconducting Accelerator Magnets containing Higher Harmonics"],"weko_creator_id":"1","weko_shared_id":1},"updated":"2023-06-20T16:00:27.415193+00:00"}
