Energy Confinement Time Scaling Law Derived from Paz-Soldan NF 2024
P. Lunia, A. O. Nelson, C. Paz-Soldan
Results from C. Paz-Soldan et al 2024 Nucl. Fusion 64 094002 demonstrate encouraging energy confinement properties for the negative triangularity scenario, similar to or exceeding…
Turbulent Transport-Limited Pedestals in Tokamaks
J. F. Parisi, D. R. Hatch, P. Y. Li +5
H-mode operation of tokamak fusion plasmas free of dangerous Type 1 edge-localized-modes (ELMs) requires a non-ELM mechanism for saturating the edge pedestal growth. One possible m…
First Access to ELM-free Negative Triangularity at Low Aspect Ratio
A. O. Nelson, C. Vincent, H. Anand +12
A plasma scenario with negative triangularity (NT) shaping is achieved on MAST-U for the first time. While edge localized modes (ELMs) are eventually suppressed as the triangularit…
Power handling in a highly-radiative negative triangularity pilot plant
M. A. Miller, D. Arnold, M. Wigram +7
This work explores power handling solutions for high-field, highly-radiative negative triangularity (NT) reactors based around the MANTA concept \cite{rutherford_manta_2024}. The d…
