[TCML] Latest TC results, and one strange one....

It looks like your "mystery spark" is just a streamer that happened to
originate from some feature near the top of the secondary coilform, rather
than from the toroid itself.
If you watch the video clip carefully, you can see corona and multiple small
streamers originating from this location. I can't clearly see the "inverted
bowls", but is there a metal flange or a sharp edge of some sort at this
I think there are two factors contributing to your "mystery streamer":
1. There is a sharp edge or point near the top of your secondary that is
causing a high field gradient;
2. Your toroid is positioned too high above the top of the secondary, and
is not providing adequate electrostatic shielding of the top of the
Your pair of deep bowls may just be too tall for the toroid diameter you are
using. It looks like the secondary may be 12" - 15" above the top of the
secondary; you might want to reduce this to 6" - 8".

Two things - first is the latest results of my ever-modifying TC. Second
thing is a mystery spark I'd ask you all to take a peak at and see what it
Firsy, here is the latest TC with an 18 inch toroid, fit nicely over an
inverted metal deep bowl, and that on top of another/identical bowl, as seen
here. Running at between 11.5 and 11.75 turns of the primary. Power supply
is 12kV 60mA through terry filter, and secondary is a 4" x 18" with about
1020 turns of 25 awg. Vacuum quentioned copper tube gap with 4 series by 2
parallel. Longest streamers are 30" sometimes 35" streamers.
Now to the second thing. Below is a video, and a series of snapshots come
from it, where a strike to the rail, also brings down this weird electric(?)
artifact seen to come down from way above the toroid, hang from the toroid,
then goes back up, during the rail strike. See
To show it is electric, and not just a camera anomoly, I also saw a single
frame in a seperate video where an identical looking trail leads from the
toroid to the leader that strikes the ground rail. See below.
Pic (screen cap from above video - look for the rail strike):
Very interested to know what this phenomenon is???
Thank you all.
