Roger; I was an engineering department chief for the manufacture of electron tubes at the Western Ecletric plant in Lee's Summit , Missouri. We also made semiconductors and sputtering is part of the operation.
All of our sputters operated in vacuum. I just rechecked with one of my former senior engineers about sputtering, and he reaffirmed that it was done in vacuum. I have no voltage control only spacing of the arcing electrode, and whether I close that gap to almost nothing or open it to where it wont fire there is no change in the arc characteristics. When you send the sample please include a simple sketch of what you are doing do that I can set it up. I am curious.
