Demo Fusor Plasma Improvement

Post by John Beutz » Sun Sep 11, 2016 10:51 pm

Over the past few days I have been working on improving the quality of the vacuum in my demo fusor, building a better and thicker grid, and making a bigger work table for the garage "lab" where I used to make transistor radios and stuff.
Much better plasma with the copper grid.
I made the grid with an old coiled bit of wire I had. First, the insulation had to be burned off.
When that was done, I soldered it all together and tried to fix some leaks in the vacuum. I do not have a TC gauge yet as per Dennis Brown's memberlist.php?mode=viewprofile&u=2384 suggestion. Since the plasma is just holding to the grid, the vacuum seems to be inadequate. But the vacuum in the chamber can only be as good as the pump pulling it, so maybe an upgrade from bare minimum is in order. I have a much larger workspace now, with room to fit more components as my experiments evolve:
