摘要: Production and identification of electron temperature gradient modes have already been reported [X. Wei, V. Sokolov, A. K. Sen, Phys. Plasmas 17, 042108 (2010)]. Now a measurement thermal conductivity via unique high frequency triple probe yielded value {chi}{sub perpendiculare} ranging between 2 10 m{sup 2}/s, which is the order several gyrobohm diffusion coefficient. This experimental result appears to agree with nonlocal obtained from rough theoretical estimation not inconsistent gyrokinetic simulation results for tokamaks. The first scaling versus amplitude fluctuation also obtained. It approximately linear, indicating strong turbulence signature.
