Thank you for the info Erik. Would you happen to have one that you do not need, or could you point me towards the eBay seller please?

Hi Erik, I'm building a similar chamber and was wondering where you got your HV feedthrough.
Nice job!

That vacuum chamber was one that I was just using for plasma generation. I am going to purchase a 2.75 inch conflat cross for the actual chamber with the proper conflat fittings.

Yes that gauge came with the vacuum pump a long time ago and I am looking for one that will work for fusion applications. The gauge would just tell me if I got to a low enough pressure for plasma to form.

I am certain the gauge is broken and is leaking oil into the chamber. When I pull a vacuum for about 5 minutes, the gauge still reads zero while plasma is created. Also at these pressures the plastic that is used to view the numbers is being pulled into a concave shape and tiny bubbles can be seen r...

Thanks for the information Preston! I will continue to try to get my chamber down to the specifications on my pump (0.3Pa or ~2.75 microns) to hopefully achieve a better effect.

Thank you Richard! I was also wondering if this would be enough to get into plasma club or would I have to drop the pressure even lower?

I was running some experiments with a steel vacuum chamber (really a steel cooking pot with acrylic on top) and I decided to make a quick grid from copper wire and use the vacuum line as a HV feed-through. My supply is the United Nuclear 25KV DC power supply and runs off a motorcycle battery. My pum...
