Towards assembly completion and preparation of experimental campaigns of Wendelstein 7-X in the perspective of a path to a stellarator fusion power plant

Abstract: The superconducting stellarator device Wendelstein 7-X, currently under construction, is the key device for the proof of stellarator optimization principles. To establish the optimized stellarator as a serious candidate for a fusion reactor, reactor-relevant dimensionless plasma parameters must be achieved in fully integrated steady-state scenarios. After more than 10 years of construction time, the completion of the device is now approaching rapidly (mid 2014). We discuss the most important lessons learned du… Show more

“…Wendelstein 7-X (W7-X) [1,2,3] is a stellarator [4]; a plasma fusion experiment to exploit the potential of controlled nuclear fusion [5] for the production of energy. The plasma is confined by a strong magnetic field inside the plasma vessel which is nested within a toroidal arrangement of magnetic coils.…”

“…Figure 2.5 shows |B| at the origin for several knots/unknots. This study can find applications to the problem of plasma confinement in experimental devices with toroidal geometry like tokamaks and stellarators [31,26,24]. …”

“…With the start of the Wendelstein 7-X experiment [1] and the coming of ITER [2], we are urged to explore the role of non-axisymmetric magnetic fields in fusion devices, for they are crucial in the control of edge localized modes (ELMs) in Tokamaks and they will necessarily influence core transport in Stellarators [3]. There is general agreement on the use of gyrokinetic theory [4] for the prediction of kinetic instabilities and transport levels in the core of fusion plasmas, however, there is not a simple prescription on how to solve this equation.…”
