Dataset goal
Learn the baseline coherent coupling between:
edge plasma heat flux
surface temperature
erosion / sublimation rate
bulk thermal fatigue cracking
This is the baseline layer for predicting PFC failure.
Required model outputs
coherence_score
decoupling_flag
Why it matters
PFC failure starts when:
heat flux stops predicting erosion rate
erosion stops predicting crack density growth
thermal cycles stop matching observed damage
This dataset establishes the normal coupling surface.
Use cases
tungsten and beryllium PFC monitoring
early warning for wall lifetime loss
fusion materials screening
maintenance planning
