Universal inIn strongly magnetized plasmas such as tokamak plasmas, turbulence develops on micro-scales in the transverse direction, typically of the order of a few Larmor radii. However, its non-linear saturation is largely governed by large scale °ows, which can capture most of the turbulent energy without driving any transverse transport [1].
