Wendelstein 7-X, undoubtedly one of the coolest (maybe the coolest?) experiments of our time, is about to start its main experimental campaign in autumn 2021. Perfect timing for you to learn what the fuss is all about - why does the magnetic field look the way it does, how does it compare to other stellarators long dismantled and still running, it what sense do we expect it to be better than a tokamak (and where will it be worse) and will stellarators ever be viable reactor candidates? Curious? Then sign up for the Masterclass Stellarators!
