Dear All,
I have used the exact same "value" caps from Cornell (CDE), and TDK
(laser pulse) on my coil at 14-15nF. I am using an 8 inch sphere as
a topload. I am getting great results from both, but there is a very
big difference between the two. The CDEs create thinner spiker
whiter arcs, sometimes multiple, that jump around like quanta.
However, the TDKs create one big thick bluish arc that rolls slowly
around the ball. I like the TDK's effect much better.
Is there another parameter having to do with a capaicitor, like how
fast it can discharge, or how they are wired in parallel, that would
explain this behavior? Why are some capacitors "better" in this way
than others?
Losses, that can be modelled as series resistance. It would be interesting
to see the waveforms in the coil in both cases. A significant difference
can be caused by quenching at the first notch or at some other notch of the
primary voltage waveform, and a difference in the losses may cause the
difference. What case results in the best spark output I don't know.
Just verify if all the connections are really identical in both cases,
particularly the settings of the spark gap.
