Integrated modeling of RF-Induced Tungsten Erosion at ICRH Antenna Structures in the WEST Tokamak
A. Kumar, W. Tierens, T. Younkin +14
This paper introduces STRIPE (Simulated Transport of RF Impurity Production and Emission), an advanced modeling framework designed to analyze material erosion and the global transp…
A scaling law of the neutral opacity and Balmer- wing shape in high-temperature plasmas
Keisuke Fujii, Masahiro Hasuo, Motoshi Goto +1
Hydrogen atoms penetrating deep inside high-temperature magnetically confined plasmas by repetitive charge-exchange collisions result in a particle source, which affects the plasma…
Evolution of radiation profiles in a strongly baffled divertor on MAST Upgrade
Fabio Federici, Matthew L. Reinke, Bruce Lipschultz +11
Plasma detachment involves interactions of the plasma with impurities and neutral particles, leading to significant losses of plasma power, momentum, and particles. Accurate mappin…
Conceptual Design of a Doppler Spectrometer for 10 m/s Cross-Field Flows in Tokamak Divertors
Keisuke Fujii, Ryuichi Sano, Tomohide Nakano +4
It has been theoretically predicted that the \ExB drift caused by the spontaneously generated potential in scrape-off-layers (SOLs) and divertors in tokamaks is of a similar size t…
