Tests confirm that Germany’s massive nuclear fusion machine really works

From Science Alert:

“At the end of last year, Germany switched on a new type of massive nuclear fusion reactor for the first time, and it was successfully able to contain a scorching hot blob of helium plasma.

But since then, there’s been a big question – is the device working the way it’s supposed to? That’s pretty crucial when you’re talking about a machine that could potentially maintain controlled nuclear fusion reactions one day, and thankfully, the answer is yes.

A team of researchers from the US and Germany have now confirmed that the Wendelstein 7-X (W 7-X) stellerator is producing the super-strong, twisty, 3D magnetic fields that its design predicted, with “unprecedented accuracy“. The researchers found an error rate less than one in 100,000.

“To our knowledge, this is an unprecedented accuracy, both in terms of the as-built engineering of a fusion device, as well as in the measurement of magnetic topology,” the researchers write in Nature Communications.

That might not sound exciting, but it’s crucial, because that magnetic field is the only thing that will trap hot balls of plasma long enough for nuclear fusion to occur.”
