Description:
- The TUFI/AETB-8 diffusion layer is the layer material with variable density just below the TUFI external surface that occurs in AETB-8. It has been proposed in many other areas prone to damage, but is not currently being used due to the thermal conductivity of the substrate and the cost of redesign and installation.
