Wendelstein 7-X (W 7-X) is the largest stellarator experiment envisaged worldwide. It is prepared in the Max-Planck-Institute for Plasma Physics in Garching near Munich, Germany. The main goal of the experiment is demonstration of the optimized stellarator concept as an appropriate route for a fusion reactor. Essential physics and technical goals of this experiment are: demonstration of stationary operation, achievement of plasma parameters which allow a reliable prediction of the properties of a future stellarator reactor plasma without striving for ignition, and generation of the magnetic confinement with superconducting modular coils in a stellarator for the first time. The optimization criteria of the coil system are described and the status of the engineering development programme for the coils which is a common task of IPP and the nuclear research center KfK in Karlsruhe are reported.
