The suppression of turbulence by the E×B shear is studied in systems with quasisymmetry using the nonlinear analysis of eddy decorrelation previously utilized in finite aspect ratio tokamak plasmas Phys. Plasmas 2, 1648 (1995). The analytically derived E×B shearing rate which contains the relevant geometric dependence can be used for quantitative assessment of the fluctuation suppression in stellarators with quasisymmetry.
T. S. Hahm (1997) studied this question.
