The separatrix operational space of next-step fusion experiments: From ASDEX Upgrade data to SPARC scenarios
Thomas Eich, Thomas Body, Michael Faitsch +13
Fusion power plants require ELM-free, detached operation to prevent divertor damage and erosion. The separatrix operational space (SepOS) is proposed as a tool for identifying acce…

Quantification of locked mode instability triggered by a change in confinement
M. Peterka, J. Seidl, T. Markovic +24
This work presents the first analysis of the disruptive locked mode (LM) triggered by the dynamics of a confinement change. It shows that, under certain conditions, the LM threshol…

Reduced model for H-mode sustainment in unfavorable drift configuration in ASDEX Upgrade
O. Grover, T. Eich, P. Manz +6
A recently developed reduced model of H-mode sustainment based on interchange-drift-Alfvén turbulence description in the vicinity of the separatrix matching experimental observatio…
