Abstract / Description:The Wendelstein 7-X stellarator, presently under construction in Greifswald, is the largest stellarator device. The W7-X has been “fully” optimised numerically, based on the concept of quasi-isodynamicity. Its key element is an optimized magnetic field configuration, generated by 50 non-planar superconducting coils. It is the mission of the project to demonstrate the reactor potential of the optimized stellarator line. In particular, stellarators can operate in steady-state, which is still difficult to achieve in nowadays tokamaks. Wendelstein 7-X aims for steady-state operation of fusion-relevant plasmas in a stellarator for the first time.
This talk gives a broad overview of the construction status of Wendelstein 7-X and outlines key elements of the future research concept. The latter is largely based on experiences obtained with the predecessor device, Wendelstein 7-AS. However, some of the future operation parameters could be predicted by numerical transport simulations.
