Low-frequency/long-wavelength density turbulence is found to be reduced withinthe volume enclosed by an electron thermal internal transport barrier generated with lower hybrid microwave heating in the JET tokamak. Theturbulence reduction coincides with a region (typically r/a<0.4) ofnegative, or reversed magnetic shear s and reduced electron thermal diffusionχe. In the tokamak edge region (r/a>0.8), the turbulenceamplitude is also reduced coinciding with large positive magnetic shears>1. Estimates of the core turbulence wavelengths (λ⊥>0.1 m) are not in agreement with expectations from electron temperaturegradient instabilities.

JETトカマクにおいて低混成マイクロ波加熱によって生成された電子熱内部輸送障壁によって囲まれた体積内で、低周波/長波長の密度乱流が低減されることが見出された。この乱流低減は、負の、または反転した磁気シア s と低減された電子熱拡散χe の領域(典型的には r/a<0.4)と一致する。トカマク周辺領域(r/a>0.8)では、乱流振幅もまた、大きな正の磁気シア>1と一致して低減される。コア乱流の波長(λ⊥>0.1 m)の推定は、電子温度勾配不安定性からの予想と一致しない。
