Thanks for the reply. I am unclear on point one above. I do not quite understand the part about:
"The opposite electrode surfase is shielded with stainess steel shield placed on the distance about 3 mm from electrode. In this case discharge will be concentrated on the surface to be cleaned. "
My glass will be fixed at the end of the tank, not rotating. The Aluminum will be evaporated from a Tungsten filament approximately 36 inches distance from the glass. I am attempting to purchase a nice HV feedthrough insulator which (I think) be at the end of the tank next to the filament.
If I understand you correctly, I need to make an aluminum plate parallel to the glass surface (kinda like a capacitor?) and charge it with the negative polarity. Won't this plate be in the way of the evaporated aluminum? That's the part I am having trouble with. Can the discharge be done from a point source located near the filament? My feedthrough insulator would make a good point source if that is possible.
