After a number of setbacks, the most expensive of which was a ruined $5000 turbopump, Mark Suppes has finally got his experiment up and running, achieving electron confinement in the world’s first amateur Polywell. Check out his pictures. There are a couple very blurry pictures of an air plasma within the copper wire-wrapped teflon Polywell inside the vacuum chamber. I believe the electron gun is the circular thing in the lower center (and slightly to the right) on the far side of the Polywell magrid, and the dark rectangle on the right is the ceramic holder of the tungsten Langmuir probe, which is collecting the data on electron confinement.
