Do we need to argue about the 3pF/metre > streamer cap? It > ought to depend on the thickness of the streamer, --- Depends very little I guess.For a flat long wire perpendicular to a g.plane,the depedence of wire diameter to capacity per meter goes in logarithmic way (about TT42 19 kv/cm on toroid and any form of of visible breakout): *************** In normal atmospheric conditions (20 C,1 bar,normal humidity factor 1) 19 Kv/cm can not support corona ignition by no means. Somehypotesis regarding this pecularity arise : 1)Toroid geometry isn't pure toroidal or geometry togather with coil body isn't defined very precisely. 2)Toroid isn't perfectly smooth but this case is hardly to belive knowing John's expertise in making them. 3)Celling,walls etc are too close and increase field to 26 kv/cm.This isn't case either I affraid. 4)Bang size energy varies or is higher.
