Diamond windows in production in Europe
The European Domestic Agency Fusion for Energy is working with a German contrator, Diamond Materials, for the production of sixty 1.1 mm thick discs with a diameter of 7 cm. Each one requires approximately six months to complete, including tests. The company is currently working at a rate of 7 to 10 discs every four months.
First the sythetic diamonds are "baked" in one of the company's 40 furnaces, a process that requires two months. Then the diamond is separated from its substrate, shaped to °ÄÃÅÁùºÏ²Ê¸ßÊÖ specifications, and polished before its quality gets confirmed through optical testing.
