First access to ELM-free negative triangularity at low aspect ratio

First access to ELM-free negative triangularity at low aspect ratio

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 triangularity is decreased below $\delta\lesssim-0.06$ , an extended period of H-mode operation with Type-III ELMs is sustained at l...
