One of the drivers for this seminar series is to get a glimpse of the many research questions, ideas, and results linked to the activities in our division. The seminars are intended to be very informal and we make plenty of room for questions and discussions.

Abstract: In this talk, I will describe the Europe's latest fusion plasma experiment, the billion-euro Wendelstein 7-X stellarator and, perhaps more importantly, the idea on which it rests. In 1951, Princeton astrophysicist Lyman Spitzer realised that magnetic field lines can be twisted without the need for a local electric current - an early anticipation of the "Berry phase" in quantum mechanics. Such magnetic fields are particularly suitable for confining ionised plasmas and are attracting renewed interest thanks to experimental results from Wendelstein 7-X, which will be described in the talk along with basic theoretical concepts.
