Re: Rectifying Action? Might it be that simple?
Reinhard , Coilers all.....Just a very uneducated GUESS as to why the
output spark length increases when using alternate Al and Cu tubing in
your spark gap. Could the Al atoms (or the combo of Al and Cu atoms)
being sputterd (blasted away) from the electrodes be combining with
gasses/vapors in the atmosphere by the spark in the gap to produce a
local 'quenching atmosphere' between the gaps? Or could it be that this
process lowers spark gap resistance?.....Anyway, very interesting
results! Have you tried using only Al tubing in a spark gap? Just
wondering.............. "May your sparks grow ever longer"
