The PNAS article has more photos and videos https://www.pnas.org/doi/10.1073/pnas.1818350116

Looking online apparently this damages the magnetron, but no one has found out why precisely. There are some pop-culture explanations that the reflected energy overloads the magnetron and so on, but I don't think anyone has done the parallel what this team has done to actually say what happens to the magnetron.

The PI has a website https://www.aaronslepkov.com/research but nothing new about this stuff there. I'm curious.

We know now why the plasma forms. I hope they're able to explain why the magnetron breaks.



Arcing?

How would one point camera at the magnetron and still keep it safe

(The plasma acts as a sort of antenna-- we maybe don't want 2 magnetrons pointing at each other :)
