Re: [TCML] Would a Tesla coil work in a vaccum?

[jhowson4@xxxxxxxxxxx]

I would think you would end up creating a giant "plasma jar", the high voltage would ionize everything even in a minimal vacuum and the plasma would eat your secondary coil to death. if anything i recommend sealing the secondary system in a pressure chamber with "sulferhexaflouide" (I think, not quite sure what the gas is called). but whatever it is, it's an excellent insulator. Alternatively you could fill a tank with mineral oil at a normal pressure. 

All in all I don't recommend sticking your coil in a vacuum.

As we know a Tesla coil is 'air cored', so what if the entire secondary and primary were enclosed in a vaccum chamber? I imagine the toroid could sit atop and outside of the vaccum chamber, and the HV supply, spark gap and C1 could also be outside the vaccum - wires through the chamber walls sealed up nice and tight. 



With no air for a 'core' would there still be streamers off the toroid, same length and brightness as there would be for the same coil if it was without the vaccum chamber?
