All windows are based on the principle of traveling wave in the ceramic region.  This approach allows reducing drastically the strength of electric field in the cerarnic region and increasing the maximum power that can be transmitted through a window without breakdown.<br /><br />　A S-band traveling-wave window at 2856 MHz was design and tested.  The high power testing results showed that more than 450 MW power with 2 μs pulse length at 5Opps repetition rate was transmitted through the window without destruction.<br /><br />　A X-band mixed-mode window with low electric field at the ceramic-metal brazing area was designed, and several of them were manufactured and are being used in PPM klystrons for a linear collider.  Those windows are compact, though being wideband and powerful.  The transmission of more than 80 MW power was achieved with 1.5 μ pulse length at 30pps repetition rate.<br /><br />　A X-band TE01-TE02 window was also designed.  This window has low electric field on the ceramic and no electric field at the ceramic-metal brazing area to be more robust for high power transmission.  The window has a simple shape, and it is compact and wideband.  A low power model was manufactured and measured.  This window has two new types of simple TE10-TE01 mode converters on both sides.  The design and the performance measurements of those converters are also described.","subitem_description_type":"Other"}]},"item_1_description_7":{"attribute_name":"学位記番号","attribute_value_mlt":[{"subitem_description":"総研大乙第112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":"数物科学研究科"}]},"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":"2002"}]},"item_creator":{"attribute_name":"著者","attribute_type":"creator","attribute_value_mlt":[{"creatorNames":[{"creatorName":"KAZAKOV, Serguei","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":"乙112_要旨.pdf","filesize":[{"value":"206.4 kB"}],"format":"application/pdf","licensetype":"license_11","mimetype":"application/pdf","url":{"label":"要旨・審査要旨 / Abstract, Screening Result","url":"https://ir.soken.ac.jp/record/622/files/乙112_要旨.pdf"},"version_id":"83cf3a56-203f-4058-975e-66d274d14316"},{"accessrole":"open_date","date":[{"dateType":"Available","dateValue":"2016-02-17"}],"displaytype":"simple","filename":"乙112_本文.pdf","filesize":[{"value":"6.2 MB"}],"format":"application/pdf","licensetype":"license_11","mimetype":"application/pdf","url":{"label":"本文","url":"https://ir.soken.ac.jp/record/622/files/乙112_本文.pdf"},"version_id":"3ab7b525-0102-4dc1-a44b-942f77d02b7a"}]},"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":"Development of New Types of High Power RF Windows","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"Development of New Types of High Power RF Windows"},{"subitem_title":"Development of New Types of High Power RF Windows","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":"622","relation_version_is_last":true,"title":["Development of New Types of High Power RF Windows"],"weko_creator_id":"1","weko_shared_id":1},"updated":"2023-06-20T14:52:38.660740+00:00"}
