Offering unsurpassed hardness, broad band optical transparency, and extremely high thermal conductivity, synthetic diamonds are the material of choice for 60 small windows that offer access to the machine for the high-frequency electromagnetic waves of ITER's electron cyclotron heating system, yet ensure a tight vacuum boundary.
The European Domestic Agency for ITER, Fusion for Energy, has procured 60 synthetic diamond discs through the German firm Diamond Materials. Now they must be polished, optically inspected, and finally joined with the diamond window unit through brazing.
See the original story on the Fusion for Energy website for all the details.
