Nonlinear modeling of the scaling law for the m/n=3/2 error field penetration threshold
Q. Hu, N. C. Logan, J. -K. Park +3
The scaling law for the n=2 error field (EF) penetration threshold is predicted numerically based on nonlinear single-fluid and two-fluid modeling using the TM1 code. The simulated…
The Role of Edge Resonant Magnetic Perturbations in Edge-Localized-Mode Suppression and Density Pump-out in low-collisionality DIII-D Plasmas
Q. M. Hu, R. Nazikian, B. A. Grierson +3
Two-fluid nonlinear MHD simulations using the TM1 code demonstrate that the formation of magnetic islands at the top and bottom of the H-mode pedestal, together with the strong scr…
Highest Fusion Performance without Harmful Edge Energy Bursts in Tokamak
SangKyeun Kim, Ricardo Shousha, SeongMoo Yang +20
The path of tokamak fusion and ITER is maintaining high-performance plasma to produce sufficient fusion power. This effort is hindered by the transient energy burst arising from th…
Wide operational windows of edge-localized mode suppression by resonant magnetic perturbations in the DIII-D tokamak
Q. M. Hu, R. Nazikian, B. A. Grierson +4
Edge-Localized-Mode (ELM) suppression by resonant magnetic perturbations (RMPs) generally occurs over very narrow ranges of the plasma current (or magnetic safety factor q95) in th…
Experimental conditions to suppress edge localised modes by magnetic perturbations in the ASDEX Upgrade tokamak
W. Suttrop, A. Kirk, V. Bobkov +9
Access conditions for full suppression of Edge Localised Modes (ELMs) by Magnetic Perturbations (MP) in low density high confinement mode (H-mode) plasmas are studied in the ASDEX…
Onset of nonlinear structures due to eigenmode destabilization in tokamak plasmas
Vinicius Duarte, Herbert Berk, Nikolai Gorelenkov +5
A general methodology is proposed to differentiate the likelihood of energetic-particle-driven instabilities to produce frequency chirping or fixed-frequency oscillations. The meth…
Total Fluid Pressure Imbalance in the Scrape-Off Layer of Tokamak Plasmas
R. M. Churchill, J. M. Canik, C. S. Chang +5
Simulations using the fully kinetic neoclassical code XGCa were undertaken to explore the impact of kinetic effects on scrape-off layer (SOL) physics in DIII-D H-mode plasmas. XGCa…
