| Abstract Scope |
Wendelstein 7-X (W7-X) is an optimized stellarator which started operation in 2015 at Greifswald, Germany. The objective is to demonstrate steady state operation of fusion-relevant hydrogen and deuterium plasmas. The divertor function is to control the plasma power and particle exhaust and is subject to heat loads by convection or thermal radiation from the plasma.
The 20mē W7-X divertor is made of 890 target elements (TEs) designed to remove a stationary heat flux of 10 MW/mē and cooled with pressurized water. The TEs are made of the Cu alloy CuCrZr heat sink armored with about 16,000 carbon fibre reinforced carbon (CFC) NB31 flat tiles as plasma facing material. The developed joining technology between tiles and heat sink is a Cu bi-layer technology. The manufacturing route of CFC and target elements will be presented. |
