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.

So... this experiment was to get a non-reactive plasma contained.
That's a crucial step to any fusion device, but we can count on the broader media, if they cover it at all, to do so in hyperbolic terms. "ENERGY CRISIS RESOLVED!"

From TFA:
Despite the fact that the machine successfully controlled helium plasma in December last year, and then the more challenging hydrogen plasma in February, no one had shown that the magnetic field was actually working as it should be.
This experiment was to see that the magnetic fields were constructed correctly. It already works apparently for containing plasma. They just wanted to see if they were doing/did it right.

Wait, they want to check their containment before setting off a fusion reaction... What's the fun in that?

Sadly, life isn't like sci-fi, and "containment" doesn't mean "preventing a nuclear explosion" but is instead a requisite state for the plasma to be in before fusion is even possible.
H-Bombs essentially use a small fission explosion as containment for the tritium-deuterium reaction that fuels the big boom.
It turns out to be really really really hard to keep particles with the same charge in close proximity.

Not just in proximity of each other, but far away from walls, windings and people which wouldn't be very happy to meet them up close, even if there aren't too many of them for now.
I like calling the fission igniter explosion a "containment". A 100t hydraulic press is also a container, I guess.

"Containment" (in this context) refers to its relationship to the object being contained.
A press is only a container if it is containing something in that might come out...
I nuclear fission reactor that fails to contain plasma is just a giant, incredible expensive metal donut...

IIRC, I think the fun is when you turn off the containment grid. BOOM!

Alternately, they should think about contacting Dr Otto Octavius for assistance.

Well, to be honest, even without this, the energy "crisis" has been been resolved for a very long time. The only remaining problem is bad management, and a disagreement over the price. Those are the direct cause of any "crisis".

No, it was to measure, using nothing more than a beam of electrons, whether the magnetic field had the right properties such that they should expect to maintain containment of a plasma.
They've reached the "looks like one bit of it should work" stage.
