Re: [TCML] largest secondary coil you'd drive with an NST



Tim,

You wrote:

I hate to ask this too - but what is the optimum aspect ratio for a
secondary?  I've run JAVATC, and have built a feeble (but pretty) classic
tesla before ... and have read but probably poorly understood a few papers. I think that I'm ready to build version two of the static-gap, NST-powered, properly filtered and protected coil. I just want to make sure that I learn
as much as possible before I start purchasing things that probably won't
suit my needs.

Please review my from previous posting as this was covered, too.

Hi Tim,

As far as height goes, optimum aspect
ratios (height vs diameter) are generally between 3:1 and
5:1 with the larger coils generally falling toward the lower
range and the smaller ones to the higher range. You should
choose a wire size that will allow you to wind 1000 to 1200
turns while maintaining the secondary's dimensions within
the optimum aspect ratio.

Hope this helps,
David
