[3dem] glow discharge vs plasma cleaning

[benoit.zuber at ana.unibe.ch]

Dear colleagues,

I often hear people saying: „Did you treat your grid with glow discharge or with plasma cleaner?” Or : ”It is absolutely essential for application XY to pretreat the grid with a plasma cleaner and not by glow discharge!”.

Can anyone explain what the difference between glow discharge and a plasma cleaning is?

According to Wikipedia, this is the same thing (https://en.wikipedia.org/wiki/Glow_discharge). The page starts with this sentence:
“A glow discharge is a plasma<https://en.wikipedia.org/wiki/Plasma_(physics)> formed by the passage of electric current<https://en.wikipedia.org/wiki/Electric_current> through a low-pressure gas”

I look forward to an interesting debate.
Ben
