1-Hour Ion Gun
Posted: Fri Jul 03, 2009 5:01 am
I just built an ion gun today to help since I haven't been able to get measurable fusion with a neutron detector. It is basically just a copper tube centered down a 1/4" npt nipple with a negative voltage fed onto that copper tube (from an NST). Gas flows between the copper tube and the 1/4" npt pipe.
At around 1500 volts, the plasma formation disappeared and a pink formation formed coating all of the metal in the chamber. This change is instant, at a certain voltage around 1500 the plasma completely disappears and turns purple. What exactly is this other formation? I have never seen anything like it before.
Also there is a very high RF field coming off of it, my tube-amplifiers across the room were going crazy and I couldn't even hear my music over the static noise. Normal plasma operation on the grid doesn't make anywhere near this much noise. It knocked out my vacuum gauge for about 5 minutes, I have no way of explaining why it suddenly started working again after a few minutes but at least it saved me some money.
I wish I could power up the grid with this installed but I need to get another variac to do this because I need one on the ion gun.
