Fast ion effects on the threshold conditions of ion temperature gradient mode and electron temperature gradient mode
Min Ki Jung, Taik Soo Hahm, Yong-Su Na +1
We investigate the fast ion effects on the threshold conditions of ion temperature gradient (ITG) mode and electron temperature gradient (ETG) mode both analytically and numericall…
Data-Driven Reduced-Order Modeling of Phase Mixing Dynamics from Particle Kinetic Simulation
Darian Figuera-Michal, Sungpil Yum, Jae-Min Kwon +1
Phase mixing is a fundamental kinetic process that governs dissipation and stability in collisionless plasmas, but its inherent filamentation in velocity space creates major challe…
Predictive study of non-axisymmetric neutral beam ion loss on the upgraded KSTAR plasma-facing components
Taeuk Moon, Tongnyeol Rhee, Jae-Min Kwon +2
We simulate ion loss induced by neutral beam injection (NBI) in three-dimensional (3D) space with high fidelity on the plasma-facing components (PFCs) of the Korea Superconducting…
Verification of Fast Ion Effects on Turbulence through Comparison of GENE and CGYRO with L-mode Plasmas in KSTAR
Donguk Kim, Taeuk Moon, Choongki Sung +7
This study presents a cross-verification of fast ion effects on turbulence through a systematic comparison of two leading gyrokinetic codes, GENE [F. Jenko et al., Phys. Plasmas 7…
