Demo Fusor

Post by Samuel Low » Wed Aug 15, 2018 6:04 am

Just to share, did a successful run of another new demo fusor with better vacuum parts and electronics. No actual fusion here, just pretty plasma confinement in the works.

Voltages are (very roughly) in order of the increasing brightness you see:
- 1500V
- 2350V
- 3125V
- 3900V
- 4700V
- 5450V
- 7000V

I am just noticing a plasma arc jet in the bottom of the grid and I am wondering if it can be used as a plasma thruster of some sort for satellite applications. Would there still be enough particles in the atmosphere in LEO (with a density of 10E-13kg/m3 roughly) to do adequate plasma confinement? Let me know your thoughts?
