This is a stellarator which is the same idea as a tokamak: Confine hydrogen with magnets and get fusion.
The magnetic field in a stellarator is crazy complicated, and was impossible to model and design before computers. With computers they were able to design it, but were unsure if they could build it.
This is a test showing that yes, they can actually build it.
In theory stellarators are simpler to get right than tokamaks, but only if you can actually design, and then make one.
