Real-time feedback control of ELM frequency using divertor gas puffing and its effects on tungsten-induced radiation and plasma performance in KSTAR
Minseok Kim, Young-Ho Lee, SangKyeun Kim +10
The edge-localized mode (ELM) frequency () was successfully controlled in real time on KSTAR using a proportional-integral (PI) feedback controller, employing a $…
Operational Space and Plasma Performance with an RMP-ELM Suppressed Edge
C. Paz-Soldan, S. Gu, N. Leuthold +14
The operational space and global performance of plasmas with edge-localized modes (ELMs) suppressed by resonant magnetic perturbations (RMPs) are surveyed by comparing AUG, DIII-D,…
Spectral analysis of spin noise in an optically spin-polarized stochastic Bloch equation driven by noisy magnetic fields
M. M. Kim, Sangkyung Lee
We provide a closed-form autocorrelation function and power spectral density (PSD) of the solution, along a prescribed probing direction, to a noisy version of an optically pumped…
Effects of Phase Difference between Instability Modes on Boundary Layer Transition
Minwoo Kim, Seungtae Kim, Jiseop Lim +3
Phase effect on the modal interaction of flow instabilities is investigated for laminar-to-turbulent transition in a flat-plate boundary layer flow. Primary and secondary instabili…
Stochastic fluctuation and transport of tokamak edge plasmas with the resonant magnetic perturbation field
Minjun J. Choi, Jae-Min Kwon, Juhyung Kim +17
We present that a statistical method known as the Complexity-Entropy analysis is useful to characterize a state of plasma turbulence and flux in the resonant magnetic perturbation…
Drop Impact on Hot Plates: Contact times, Lift-off and the Lamella Rupture
Sang-Hyeon Lee, Kirsten Harth, Maaike Rump +4
When a liquid drop impacts on a heated substrate, it can remain deposited, or violently boil in contact, or lift off with or without ever touching the surface. The latter is known…
Experimental evidence of the non-diffusive avalanche-like electron heat transport events and their dynamical interaction with the shear flow structure
Minjun J. Choi, Hogun Jhang, J. -M. Kwon +12
We present experimental observations suggesting that the non-diffusive avalanche-like events are a prevalent and universal process of the electron turbulent heat transport in tokam…
The effect of time-varying flow-shear on the nonlinear stability of the boundary of magnetized toroidal plasmas
Youngmin Oh, Hyung Ju Hwang, Michael Leconte +1
We propose a phenomenological yet very general model in a form of generalized complex Ginzburg-Landau equation to understand the dynamics of the quasi-periodic fluid instabilities…
BOUT++: Recent and current developments
B. D. Dudson, A. Allen, G. Breyiannis +12
BOUT++ is a 3D nonlinear finite-difference plasma simulation code, capable of solving quite general systems of PDEs, but targeted particularly on studies of the edge region of toka…
