Study of low-frequency core-edge coupling in a tokamak: III. Core-localized MHD continuum pulsations \& distant forced reconnection
Andreas Bierwage, Panith Adulsiriswad, Gyungjin Choi +2
Slow magnetoacoustic pulsations (SMAPs) are found in MHD simulations of a tokamak plasma whose safety factor near the center is flat and slightly above unity (). S…
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…
