Hello all!
I discovered why I had a crappy vacuum. The copper gaskets hadn't made a good seal. I guess it's because of my 12 year old arms not being able to fully tighten the bolts. So, I went to LDS vacuum for some viton gaskets along with 12 point bolts. After replacing the gaskets, I hooked the entire system up to my Edwards e2m5 pump. I pumped it down for 15 minutes and was astonished to see that I had reached 20 microns. Out of curiosity, I gave around 30kv from my 50kv power supply and got the most beautiful, white plasma that filled the entire chamber. Star mode at last! I tried to take a picture, but it was far to bright. At that point, the pressure had rose to 280 microns do to the plasma evaporating contaminates on the grid. I plan to test my diffusion pump and supply some pictures later today.
If you have any questions, concerns, or suggestions they would be much appreciated.

Congrats, good work. Just make sure you not looking directly at the plasma at 30 kV as you are probably producing a significant amount of xrays at that voltage.
