Physics insights from a large-scale 2D UEDGE simulation database for detachment control in KSTAR
Menglong Zhao, Xueqiao Xu, Ben Zhu +8
A large-scale database of two-dimensional UEDGE simulations has been developed to study detachment physics in KSTAR and to support surrogate models for control applications. Nearly…
Quantifying Resolution Limits in Pedestal Profile Measurements with Gaussian Process Regression
Norman M. Cao, David R. Hatch, Craig Michoski +4
Edge transport barriers (ETBs) in magnetically confined fusion plasmas, commonly known as pedestals, play a crucial role in achieving high confinement plasmas. However, their defin…
Detachment control in KSTAR with Tungsten divertor
Anchal Gupta, David Eldon, Eunnam Bang +7
KSTAR has recently undergone an upgrade to use a new Tungsten divertor to run experiments in ITER-relevant scenarios. Even with a high melting point of Tungsten, it is important to…
Latent Space Mapping: Revolutionizing Predictive Models for Divertor Plasma Detachment Control
Ben Zhu, Menglong Zhao, Xue-Qiao Xu +4
The inherent complexity of boundary plasma, characterized by multi-scale and multi-physics challenges, has historically restricted high-fidelity simulations to scientific research…
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…
