Re: Neutron Club Application - Erik Smith
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?

Re: Neutron Club Application - Erik Smith
Hi Erik, I'm building a similar chamber and was wondering where you got your HV feedthrough.
Nice job!
Nice job!

Re: First Plasma
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.

Re: First Plasma
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.

Re: First Plasma
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...

Re: First Plasma
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.

Re: First Plasma
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?

First Plasma
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...
