Lockheed-Martin’s fusion experiment

Years ago I did a lot of cusp confinement work. In Lockheed-Martin’s device (CFR T4B) the line cusps that pass over the internal rings experience bad magnetic curvature and this will excite instabilities. This turbulence will produce plasma losses to the wall and broaden the cusps. Lockheed-Martin underestimates how wide their cusps will be.
