10Measurement of Ion Cyclotron Emissions by Using High-Frequency Magnetic Probes in the LHD显示文摘Two pairs of high-frequency magnetic probes were installed in the Large Helical Device (LHD).During the injection of a perpendicular neutral beam,ion cyclotron emissions (ICEs) with the fundamental frequency corresponding to the ion cyclotron frequency at the plasma edge were detected,which are the same type of ICE as measured with the former spare ion cyclotron range of frequencies (ICRF) heating antennas.This type of ICE was further investigated with regard to the phase and intensity of signals.Another type of ICE was found in the LHD,and these ICEs were synchronized with bursts of toroidicity induced Alfv'en eigenmodes (TAE) and the rise of intensity of lost ion flux.Therefore the source of these ICEs was thought to be the particles transferred from the core to the outer region of plasma by the TAE bursts.The frequency of ICEs induced by the TAE bursts increases linearly with the magnetic field strength,since the ion cyclotron frequency increases with the magnetic field strength.Kenji SAITO Ryuhei KUMAZAWA Tetsuo SEKI Hiroshi KASAHARA Goro NOMURA Fujio SHIMPO Hiroe IGAMI Mitsutaka ISOBE Kunihiro OGAWA Kazuo TOI Masaki OSAKABE Masaki NISHIURA Tsuguhiro WATANABE Satoshi YAMAMOTO Makoto ICHIMURA Takashi MUTOH 2013Plasma Science and Technology2013,15,3:0
11Study 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
