Overall TSG objective: Perform comparative assessment of high-Z and liquid metal PFCs
Thrust 1 - Understand lithium surface-science for long-pulse PFCs
- Assess impact of more complete Li coverage
- Use the new Material Analysis and Particle Probe (MAPP) and laboratory studies to link tokamak performance to PFC surface composition
Thrust 2 - Unravel the physics of tokamak-induced material migration and evolution
- Confirm erosion scalings and evaluate extrapolations
- Determine migration patterns to optimize technical solution
Thrust 3 - Establish the science of continuous vapor-shielding
- Determine the existence and viability of stable, vapor-shielded divertor configurations
- Determine core compatibility and extrapolations for extended durations and next-step devices
