In the EBWH/CD experiments on QUEST, the O-X-B mode conversion scenario was selected for plasma current sustainment in rather low-density plasmas. A new phased-array antenna system was proposed to launch a pure elliptically-polarized O-mode in the oblique injection. The prototype antenna system was designed and its performance was checked at low power test facilities. Good focusing and steering properties were confirmed in the low power test.本誌: 電気学会論文誌A（基礎・材料・共通部門誌） Vol.132 No.7 （2012） 特集：The 16th International Workshop on Spherical Tori 2011本誌掲載ページ: 511-516 p原稿種別: 論文／英語電子版へのリンク: https://www.jstage.jst.go.jp/article/ieejfms/132/7/132_511/_article/-char/ja/ Show more
