Edge turbulence transport during ELM suppression with n = 4 resonant magnetic perturbation on EAST

Edge turbulence transport during ELM suppression with n = 4 resonant magnetic perturbation on EAST

The edge turbulence characteristics and the induced radial transport have been investigated in edge localized mode (ELM) suppression by using the n = 4 resonant magnetic perturbation coils on EAST, with q 95 = 3.6 and the electron collisionality ν e ∗ ≈ 0.5. During ELM suppression, the edge turbulen...

Zusammenfassung:The edge turbulence characteristics and the induced radial transport have been investigated in edge localized mode (ELM) suppression by using the n = 4 resonant magnetic perturbation coils on EAST, with q 95 = 3.6 and the electron collisionality ν e ∗ ≈ 0.5. During ELM suppression, the edge turbulence is enhanced dramatically, as measured by the reciprocating probe and the poloidal correlation reflectometry. In the near SOL, the low frequency turbulence (
