question about conical secondary
Mates, Sat Sept 29 2007, 08:45PMHi TC people,
do you somebody know what was the exact reason why Nicola Tesla used conical secondary as kind of progressive design and why non of you guys are not experimenting with this shape?
Ok people, I see you have probably no idea why the conical shape should be better for generating HV. Let me make one speculation: Electrons are increasing their energy by every turn of the secondary. In case these turns are also changing diametrically (becoming smaller) it could lead to an additional increase in the enrgy - simillar like when figure skater is doing a piruet. What do you think - is this a complete nonsence ?

The Griffith Observatory has a cone shape coil. Here are a few links:

I think the main reason that no one uses a conical secondary is that it would be a PITA to wind it...
Also, I am pretty sure that the Griffith Observatory ripped out their coil when they did their huge remodel, and replaced it with a new one, although I haven't seen it with my own eyes.

Its the same coil with upgraded components (Syncro-RSG, Poly Caps).Also, I am pretty sure that the Griffith Observatory ripped out their coil when they did their huge remodel, and replaced it with a new one, although I haven't seen it with my own eyes.

Derek Woodroffe's Cotton Tess uses a conical secondary.
I can imagine that it is easier to find straight bits of pipe than conical bits of pipe.
