The new fusion reactor Wendelstein 7-X finished its construction on October 2015. Experimentation with Germany’s newest fusion reactor is beginning to heat up, to temperatures of around 80 million degrees Celsius, to be precise.
Having fired up the Wendelstein 7-X to produce helium plasma late last year, researchers have built on their early success to generate its first hydrogen plasma, an event they say begins the true scientific operation of the world’s largest fusion stellarator.
