Re: Rectifying Action? Might it be that simple?
Hello Rienhard,
I remember the post well. There was a bit of discussion going on about
aluminum
conductors and rf currents in TC use. Mike's thought of the oxide barrier in
conjunction with the Cu possibly creating a rectification is interesting.
Is there
a way to measure the rectified gap to confirm this? It seems the static
Cu-Al is
easy enough to throw together. Maybe some on the list with the right measuring
tools can pop one together to verify this? If this truly does enhance gap
quenching, then I can at least imagine a rotary application with a Cu-Al gap
series'd with it.
Thanks for posting,
Bart
