Develop high-confinement DIII-D hybrid scenario with KSTAR operational constraints
2024 Research Campaign, Task Force: W Compatible Steady State Scenarios
Purpose of Experiment
The wall of a tokamak divertor will be subject to high power and heat fluxes in a future reactor. If the peak flux is too high, it risks damage to the wall material. Past experiments in existing machines have predicted a high heat flux and narrow heat profile in reactors, but more recent experiments indicate that new effects seen at higher pressure might change how the peaks scale, easing the heat-flux challenge. Understanding how the plasma parameter profiles in and near the divertor change with changing inputs like plasma current, magnetic field, and heating power is essential for designing a reactor.
