Wendelstein 7-X sets new performance records in nuclear fusion research
On the path toward a fusion power plant, stellarators are among the most promising concepts. In the future, they could generate usable energy by fusing light atomic nuclei. This reaction must take place in a plasma — a hot gas of ionized particles heated to many tens of millions of degrees Celsius. Stellarators use magnetic confinement to hold the plasma: the plasma is trapped by a complex and powerful magnetic field, floating inside a donut-shaped vacuum chamber. With Wendelstein 7-X (W7-X), the Max Planck Institute for Plasma Physics (IPP) in Greifswald, with support from the European fusion consortium EUROfusion, is operating the world's ...
