These are the details of experiments that I have done.
Please note the dates these were written and realize that much could have changed in that short time. If something seems wrong in light of new or better information, it probably is.

This paper presented a model that suggests that the self capacitance of the primary inductor is around 150 pF. This has since been shown to be very wrong. The ringing is now believed to be caused by parasitics along with a much lower primary capacitance value. Also some of the very high currents measured may be due to the fiber-optic transducers saturating. This caused them to report much higher than actual currents in the very high-frequency high-current cases. The newer plane antenna probes show much more believable values.
Analysis of Top and Bottom Currents in the Tesla Coil Secondary Inductor.
Note that new information sheds far greater light on secondary voltages and currents so some of the conclusions in the above paper are out of date.
