Moderators cannot be offended ;-))
If the base of the secondary, strike rails, filters, etc. are not very well
and effectively grounded against RF, the radiation can be dramatic. The AC
wiring may tend to become a ground path if there is not a good REAL RF ground.

Chicken wire is good for arcs since it does prevent them from going
further. I wonder what the skin depth of that wire is like and if the very
high frequency 10MHz, 100MHz, and GHz+ noise frequencies will be conducted
or just radiated off it. Maybe they will be absorbed??? I am not sure.
Perhaps your setup can answer this for us. Looking forward to seeing what
you find.

The arc to ground currents are very high so you get powerful EMI pulses...
Welcome to the list!!
Cheers,
