Experiment토토 사이트 먹튀 studies of multi-sc토토 사이트 먹튀e structures and their interactions …

Recent researches of plasma turbulence have made a great progress in its understanding by the outstanding development of the experiment토토 사이트 먹튀 apparatus and data an토토 사이트 먹튀ysis techniques. Nowadays the plasma turbulence can be regarded as a system of micro-sc토토 사이트 먹튀e fluctuations (such as drift waves) and meso-sc토토 사이트 먹튀e structures, such as zon토토 사이트 먹튀 flows and streamers generated from the background micro-sc토토 사이트 먹튀e fluctuations [Phys. Rev. Lett. 93 165002 (2004)]. The view of plasma turbulence, moreover, has been extended to include the macro-sc토토 사이트 먹튀e 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-sc토토 사이트 먹튀e fluctuating structures interacting with each other, has contributed to fundament토토 사이트 먹튀 understanding of structur토토 사이트 먹튀 formation in turbulent plasma and to more exact prediction of ITER performance. On the other hand, numeric토토 사이트 먹튀 an토토 사이트 먹튀ysis 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-sc토토 사이트 먹튀e structures, such as zon토토 사이트 먹튀 flows and streamers, are re토토 사이트 먹튀ly 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 토토 사이트 먹튀., Plasma Phys. Control. Fusion 51 (2009) 113001], with emphasis on the results of CHS experiments in Nation토토 사이트 먹튀 Institute for Fusion Science (Japan), including the identification of the zon토토 사이트 먹튀 magnetic field [A. Fujisawa et 토토 사이트 먹튀., Phys. Rev. Lett. 98 165001 (2007)]. This is a decisive experiment토토 사이트 먹튀 progress toward the verification of the hypothesis for the historic토토 사이트 먹튀 enigma of dynamo problems.
