Safety factor and turbulence dynamics dependence of the L-H power threshold on DIII-D

Journal Article Yan, Z. ; Mckee, G. R. ; Gohil, P. ; ... - Physics of Plasmas

The L-H transition power threshold (PLH) is discovered to have a vital dependence on q₉₅, at n_e ~ 3.2 × 10¹⁹ m^-3 on DIII-D. Comprehensive 2D turbulence and flow measurements in the plasma edge reveal the co-existence of two frequency bands of broadband modes across the L-H transition with higher flow shear at higher q₉₅, which can help explain the linear decrease in PLH as q₉₅ is increased from 3.5 to 4.9. Density fluctuation measurements by beam emission spectroscopy at higher q₉₅ show that the lower frequency band (<20 kHz) of the broadband modes propagates in the ion diamagnetic directionmore »« less

Particle transport in low-collisionality H-mode plasmas on DIII-D

Journal Article Mordijck, Saskia ; Wang, Xin ; Doyle, Edward J. ; ... - Nuclear Fusion

In this article we show that changing from an ion temperature gradient (ITG) to trapped electron mode (TEM) dominant turbulence regime (based on linear gyrokinetic simulations) results experimentally in a strong density pump-out (defined as a reduction in line-averaged density) in low collisionality, low power H-mode plasmas. We vary the turbulence drive by changing the heating from pre-dominantly ion heatedusing neutral beam injection to electron heated using electron cyclotron heating, which changes the T_e/T_i ratio and the temperature gradients. Perturbed gas puff experiments show an increase in transport outside ρ = 0.6, through a strong increase in the perturbed diffusionmore »« less

Pedestal Bifurcation and Resonant Field Penetration at the Threshold of Edge-Localized Mode Suppression in the DIII-D Tokamak

Journal Article Nazikian, R. ; Paz-Soldan, C. ; Callen, J. D. ; ... - Physical Review Letters

Rapid bifurcations in the plasma response to slowly varying n=2 magnetic fields are observed as the plasma transitions into and out of edge localized mode (ELM) suppression. The rapid transition to ELM suppression is characterized by an increase in the toroidal rotation and a reduction in the electron pressure gradient at the top of the pedestal which reduces the perpendicular electron flow to near zero. These events occur simultaneously with an increase in the inner wall magnetic response. These observations are consistent strong resonant field penetration of n=2 fields at the onset of ELM suppression, based on extended MHD simulationsmore »« less

L-mode validation studies of gyrokinetic turbulence simulations via multiscale and multifield turbulence measurements on the DIII-D tokamak

Journal Article Rhodes, T. L. ; Holland, C. ; Smith, S. P. ; ... - Nuclear Fusion

A series of carefully designed experiments on DIII-D have taken advantage of a broad set of turbulence and profile diagnostics to rigorously test gyrokinetic turbulence simulations. In this paper the goals, tools and experiments performed in these validation studies are reviewed and specific examples presented. It is found that predictions of transport and fluctuation levels in the mid-core region (0.4 < ρ < 0.75) are in better agreement with experiment than those in the outer region (ρ ≥ 0.75) where edge coupling effects may become increasingly important and multiscale simulations may also be necessary. Validation studies such as these aremore »« less
