Demo fusor research possibilities??

For a science fair project a friend and I are constructing a demo fusor. We analyzed our system (which simply lacks the rubber seal for the chamber) and have determined that the only thing we can adjust is the voltage input to the inner and outer grid. We had some research ideas, mainly attempting t...

Inner grid insulation - ceramic VS nylon?

I plan on using a 1" nylon spacer as my inner grid feedthrough insulator (outside of the chamber) - should I be using ceramic instead??

Liquid dialectrics

I am planning on constructing the entirety of my high voltage line in the next couple days, and read a couple posts here and on Physics Stack Exchange that described MOTs to be very inefficient, using them for longer periods of time could end up with them burning out. I decided to look into some liq...

Re: Usage of brass in a demo fusor

Thanks Richard.
I also have a length of 1/2” nylon reinforced vinyl tubing, the barbs don’t fit snuggly on their own. Just making sure, I have to use clamps on these connections, right?

Usage of brass in a demo fusor

I recently stopped by a Home Depot, and picked up some 1/2” hose barbs and adapters for my demo fusor. I remembered though, that brass internals in vacuum systems were not ideal. I read that brass and it’s zinc coating usually outgass easily (my demo fusor will be running @50 microns), and don’t kno...

Hello from Panama

Hello, my name is John Doe (yes, don't laugh) and I am a high school student in Panama City, Panama. I am planning to build a demo fusor for a science fair, and then proceed to build a full on neutron producing fusor. I have browsed the forums for a while now and have already taken apart two microwa...
