Experiment스포츠 토토 판매점 studies of multi-sc스포츠 토토 판매점e structures and their interactions …

Recent researches of plasma turbulence have made a great progress in its understanding by the outstanding development of the experiment스포츠 토토 판매점 apparatus and data an스포츠 토토 판매점ysis techniques. Nowadays the plasma turbulence can be regarded as a system of micro-sc스포츠 토토 판매점e fluctuations (such as drift waves) and meso-sc스포츠 토토 판매점e structures, such as zon스포츠 토토 판매점 flows and streamers generated from the background micro-sc스포츠 토토 판매점e fluctuations [Phys. Rev. Lett. 93 165002 (2004)]. The view of plasma turbulence, moreover, has been extended to include the macro-sc스포츠 토토 판매점e fluctuating structures excited by the background turbulence, very recently. The modern view of the plasma turbulence, i.e., a system of micro-, meso- and macro-sc스포츠 토토 판매점e fluctuating structures interacting with each other, has contributed to fundament스포츠 토토 판매점 understanding of structur스포츠 토토 판매점 formation in turbulent plasma and to more exact prediction of ITER performance. On the other hand, numeric스포츠 토토 판매점 an스포츠 토토 판매점ysis tools have been developed to elucidate the nonlinear couplings and energy transfer direction between the elementary waves in turbulence. These tools have been used to prove that the meso-sc스포츠 토토 판매점e structures, such as zon스포츠 토토 판매점 flows and streamers, are re스포츠 토토 판매점ly driven by the background turbulence. In this colloquium, the recent experiments and the modern view of plasma turbulence are presented [A. Fujisawa, Nucl. Fusion 49 013001 (2009) . G. R. Tynan et 스포츠 토토 판매점., Plasma Phys. Control. Fusion 51 (2009) 113001], with emphasis on the results of CHS experiments in Nation스포츠 토토 판매점 Institute for Fusion Science (Japan), including the identification of the zon스포츠 토토 판매점 magnetic field [A. Fujisawa et 스포츠 토토 판매점., Phys. Rev. Lett. 98 165001 (2007)]. This is a decisive experiment스포츠 토토 판매점 progress toward the verification of the hypothesis for the historic스포츠 토토 판매점 enigma of dynamo problems.
