Operation above the Greenwald density limit in high performance DIII-D negative triangularity discharges
O Sauter, R. Hong, A. Marinoni +9
The density limit in strongly-shaped negative triangularity (NT) discharges is studied experimentally in the DIII-D tokamak. Record-high Greenwald fractions are obtained, usi…

Runaway Electron Seed Formation at Reactor-Relevant Temperature
C. Paz-Soldan, P. Aleynikov, E. M. Hollmann +5
Systematic variation of the pre-disruption core electron temperature (Te) from 1 to 12 keV using an internal transport barrier scenario reveals a dramatic increase in the productio…
