Your waveform has saved me an experiment (mixed feelings). The first part of the WF shows an exponential decrease, which we would expect if the loss was caused by resistance, but it then becomes linear, which means that the gap voltage drops are determining the loss. The quasi-exponential part is then probably caused by a combination of resistance plus gap voltage drop.
I simulated this in MicroCap using 1N4007 diodes back-to-back to represent the gap and charging the cap to a voltage which gave a waveform very similar to yours, which turned out to be 40 volts. (C=50nF and L=70uH, with a charging voltage of 10k.) This would tend to indicate that the gap voltage drop (cathode plus anode) is of the order of 175 volts, and is pretty constant with current. If you send me your voltage, L and C I'll run it for your coil and get a better result.
This is interesting stuff. ---Carl
My vortex gap is documented here: http://www.laushaus.com/tesla/vortexgap.htm And the simpler sucker gap is here: http://www.laushaus.com/tesla/onegap.htm Sorry about the outdated links in the archives...

Do you know if the gap voltage drop has been measured? Sounds difficult. Where can I find out more about Gary Lau's sucker/vortex gap? Sounds cool. I'm using a blown annular gap that works nicely.<snip!>_______________________________________________ Tesla mailing list Tesla@xxxxxxxxxx http://www.pupman.com/mailman/listinfo/tesla
