1Study of High Power ICRF Antenna Design in LHD显示文摘In large helical device (LHD), antenna loadings are different for minority ioncyclotron heating (MICH with 38.47 MHz) and mode-converted ion Bernstein wave heating(MC-IBW with 28.4 MHz), and it is necessary to improve antenna loading with low heatingefficiency to avoid arching on transmission line. To design a new ion cyclotron range of frequencies(ICRF) antenna in LHD, calculation for a simple antenna model is conducted usingthree-dimensional electrical magnetic code (high frequency structure simulator, HFSS) for anwater loading as an imaginary plasma with low heating efficiency. At resonant frequencies,antenna loading is sensitive to strap width, and resonant frequencies are strongly related tostrap height. There is no differences of RF current profile on the strap surface between resonantfrequency and non-resonant frequency. The strap should be perpendicularly placed against themagnetic field line, since Faraday-shield angle will lead to a decrease in the effective antenna height.Hiroshi KASAHARA Tetsuo SEKI Kenji SAITO Ryuhei KUMAZAWA Takashi MUTOH Goro NOMURA Fujio SHIMPO Shin KUBO Takashi SHIMOZUMA Yasuo YOSHIMURA Hiroe IGAMI Hiromi TAKAHASHI 赵燕平 Takuya OOSAKO Yuichi TAKASE 2010Plasma Science and Technology2010,12,1:0
