Novel approach to general curvilinear coordinates for plasma fluid applications
Federico D. Halpern Tess N. Bernard, Oleksandr Koshkarov, Ronald E. Waltz
In general geometry, plasma fluid equations include nonlinear geometric sources associated with fictitious forces, which pose significant challenges to computer simulations. We ref…
Ultrafast proton radiography of the magnetic fields generated by a laser-driven coil current
Lan Gao, Hantao Ji, Gennady Fiksel +3
Magnetic fields generated by a current flowing through a U-shaped coil connecting two copper foils were measured using ultrafast proton radiography. Two 1.25 kJ, 1-ns laser p…
Improved Particle Confinement with Resonant Magnetic Perturbations in DIII-D Tokamak H-Mode Plasmas
N. C. Logan, Q. Hu, C. Paz-Soldan +9
Experiments on the DIII-D tokamak have identified a novel regime in which applied resonant magnetic perturbations (RMPs) increase the particle confinement and overall performance.…
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…
Variability of MHD Instabilities in Benign Termination of High-Current Runaway Electron Beams in the JET and DIII-D Tokamaks
C. F. B. Zimmermann, C. Paz-Soldan, G. Su +14
Benign termination, in which magnetohydrodynamic (MHD) instabilities deconfine runaway electrons (REs) following hydrogenic injections, is a promising strategy for mitigating dange…
