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…
