"In total, the team produced 250 coils, 25 of which failed either due to human error or challenges in the manufacturing process that left the coils with subpar electrical or mechanical properties. Izquierdo Bermúdez says that even the smallest imperfection can compromise a coil. In one instance, a coil had to be discarded because a single metal particle trapped between the coil and one of its protective components was suspected of interfering with its performance."

Cutting edge material science like this goes a long way to explaining the cost of >USD1.5b to upgrade the LHC...

The title omits the “How” at the beginning.

It’s a Hacker News quirk. I forgot who it was, but one of the people who writes the heuristics for Hacker News submissions decided that, in order to reduce clickbait titles, submissions that start with “How …?” must be rewritten to remove the question that may or may not be answered in the article itself. Sometimes it helps, but most of the time it back fires, see these:

The filtering only happens at submission time.

The submitter can edit the title to put “How” or other filtered expressions back into it.

		Expecting submitters to know how an undocumented feature works and how to work around it seems uncharitable.

Can we use these magnets for smaller stellarators?

		They'd be worse than HTS magnets.
