Technology Issues
High power density
- ~5 MW/m2 neutron wall load for D-T
- ~2 MW/m2 surface heat load for D-3He
Liquid walls
- Linear geometry better than toroidal for flow patterns (vertical?) and impurity control
Magnets
- Normal (Cu) conductors possibly feasible at ~2 T
- High-temperature superconductors nearly available at FRC-relevant performance
Generic fusion issues (materials, blankets, etc.)
