Optimisation of target plates for the W7-X divertor at stationary operation
The open diverter structure of the Wendelstein 7-X stellarator allows an effective particle and energy exhaust for a wide range of plasma and magnetic parameters. Ten 3-D-shaped surfaces are located along the helical edge of the five-fold rotational symmetry magnetic configuration of the machine. The plasma outflow concentrates onto the target plates, so that the plasma is decoupled from the wall. The target plates are designed to withstand a maximum stationary heat flux of 10 MW/square metre. The present optimised design of the target plates, which takes into account the latest physics results, the requirements of the heating and diagnostics systems, the manufacturing costs and the mounting operations in order to build a technically reliable system, is presented.
