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…
Achievement of highly radiating plasma in negative triangularity and effect of reactor-relevant seeded impurities on confinement and transport
L. Casali, D. Eldon, T. Odstrcil +10
The first achievement of highly radiating plasmas in negative triangularity is shown with an operational space featuring high core radiation at high Greenwald fraction obtained wit…
First Access to ELM-free Negative Triangularity at Low Aspect Ratio
A. O. Nelson, C. Vincent, H. Anand +12
A plasma scenario with negative triangularity (NT) shaping is achieved on MAST-U for the first time. While edge localized modes (ELMs) are eventually suppressed as the triangularit…
Power handling in a highly-radiative negative triangularity pilot plant
M. A. Miller, D. Arnold, M. Wigram +7
This work explores power handling solutions for high-field, highly-radiative negative triangularity (NT) reactors based around the MANTA concept \cite{rutherford_manta_2024}. The d…
Error Field Predictability and Consequences for ITER
Matthew Pharr, Nikolas Logan, Carlos Paz-Soldan +2
ITER coil tolerances are re-evaluated using the modern understanding of coupling to least-stable plasma modes and an updated center-line-traced model of ITER's coil windings. This…
Design of Passive and Structural Conductors for Tokamaks Using Thin-Wall Eddy Current Modeling
A. F. Battey, C. Hansen, D. Garnier +5
A new three-dimensional electromagnetic modeling tool ThinCurr has been developed using the existing PSI-Tet finite-element code in support of conducting structure design work for…
Compressional Alfvén eigenmodes excited by runaway electrons
Chang Liu, Dylan P. Brennan, Andrey Lvovskiy +3
Compressional Alfvén eigenmodes (CAE) driven by energetic ions have been observed in magnetic fusion experiments. In this paper, we show that the modes can also be driven by runawa…
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…
