Yes, that seems to be the real article. The MSN piece is useless. Basically, their idea (which mostly seems to work) is that they can wind a ribbon of superconductor material into a magnet with no electrical insulation between the layers of ribbon. Apparently the ribbon is superconductive along its length (I'm reading between the lines here), and hence the electrical insulation is unnecessary. Also, they were using REBCO superconductors, which work as somewhat higher temperatures (20K instead of 4K). While this class of superconductors is not new, apparently they hadn't been used in fusion experiments before. Can anyone with more knowledge of superconductors chime in?
