The projects goal is not to build a reactor but to study plasma physics. I'd guess the diamond window is surely industrial diamonds. Fun fact as well: There are inner plates for shielding which are screwed into place. The question is: So you have a shield to protect from very high temperatures but also a screw on the same side. How do you protect the screw? You put a diamond coating over it. :) Also, of course we could do it cheaper now. The project began around 20 years ago and had much luck, because there were many occassions were the techhnology needed to build the Wendelstein was just invented.
