Creative commons, share-alike with attribution, is flexible enough for wikipedia. The most illustrative of the above images i think are
https://focusfusion.org/index.php/gallery/image_med/66/
https://focusfusion.org/index.php/gallery/image_med/14/
https://focusfusion.org/index.php/gallery/image_med/111/
but there should be an image, specifically for the focus fusion wikipedia article, that illustrates the magnetic field effect that distinguishes focus fusion from the more rudimentary DPF devices. if i remember correctly, there was such an image in Eric’s google tech-talks video.
