Preliminary
H.-G. Moser MPI, Munich
Material Variations
There are probably good reasons to keep AlN for the cooling contacts.
In all designs except 1) these are small plates of uniform thickness, not so expensive
For the wings more variations are possible:
AlN of lower conductivity (120 W/mK, 160 W/mK): This variation is cheaper and
easier to machine. Has a fairly high thermal conductivity and good CTE match.
Al2O3: raw material is cheaper than AlN. Machining is not much different from AlN, worse
CTE mismatch and rather low thermal conductivity.
Quartz/glasses: Probably like Al2O3, low thermal conductivity (Borofloat !)
FR4, glass fibre reinforced peek or similar materials: These materials are probably
very cheap and easy to machine. The thermal conductivity is bad, CTE mismatch rather
large.
CFK (carbon fibre) Remark: I would avoid electrically conductive material….
