Study of Low-Frequency Core-Edge Coupling in a Tokamak: I. Experimental Observation in KSTAR
Wonjun Lee, Andreas Bierwage, Seungmin Bong +6
Double-peaked fishbone events across multiple KSTAR discharges are investigated. The normalized beta and the edge safety factor under which the f…
Study of Low-Frequency Core-Edge Coupling in a Tokamak: II. Spatial Channeling & Focusing In Antenna-Driven MHD
Andreas Bierwage, Wonjun Lee, Young-chul Ghim +7
Motivated by evidence for core-edge coupling in the form of double-peaked fishbone-like low-frequency modes () in KSTAR, which exhibit synchronized Alfvénic…
Bright Spot Characterization of Low dI/dt X-pinch Plasmas using Soft X-ray Spectroscopy with Bennett Relation
YeongHwan Choi, Muhyeop Cha, Hakmin Lee +8
This study investigates the characteristics of X-pinch plasmas driven under low current rise rate () conditions using soft x-ray spectroscopy combined with the Bennett relat…
Construction and analysis of guiding center distributions for tokamak plasmas with ambient radial electric field
Andreas Bierwage, Philipp Lauber, Noriyoshi Nakajima +8
The contribution of a time-independent toroidally-symmetric radial electric field is implemented in VisualStart [Comp. Phys. Comm. 275 (2022) 108305; arXiv:2111.08224], a cod…
Will shifted and truncated Maxwellian EVDF near the wall exhibit different electron currents?
Yegeon Lim, Young-chul Ghim
Experiments to explore the predicted consequences on the I-V characteristics of a Langmuir probe based on the fluid approach for electrons and the electron Bohm criterion are condu…
Enhancing Disruption Prediction through Bayesian Neural Network in KSTAR
Jinsu Kim, Jeongwon Lee, Jaemin Seo +3
Disruption in tokamak plasmas, stemming from various instabilities, poses a critical challenge, resulting in detrimental effects on the associated devices. Consequently, the proact…
