Thank You Richard.
The pump indicates that it can go down to 3 X 10^-1 Pa, or 2.25 X 10^-3 mmHg (2.25 microns). I realize that this magnitude may not be reached, but it seems to me that it should be able to pump down to <100 microns, where one could get a plasma. I have attached the gauge to the vacuum pump inlet.
I will start posting in the vacuum category for this question ( I will copy and paste when I find some time).
Thank you again.
