Theoretical command
Check command of type II superconductivity: critical current density, flux pinning, AC losses, REBCO tape versus NbTi wire, and how Tc and field margins constrain a usable product.
Evidence to listen for
- Explains the underlying theory at the level the role demands, and can go a layer deeper when pushed
- Knows which results are established and which are contested
- Distinguishes their own contribution from the field's
- Comfortable saying where the theory runs out
Five-point scoring guide
Recites terminology without understanding; cannot go one layer deeper.
Surface familiarity; conflates established results with speculation.
Solid grasp of the core theory; thin at the frontier.
Strong command; separates settled results from open questions.
Explains quench propagation, cryogenic load budgets and field homogeneity limits fluently, tying each physical constraint to a concrete user-facing consequence.
