Re: Best cap size for a sync gap

Hi Gerry,

Gary's SLTR static gap coil seems to run at the peak in the AC voltage.  He 
page is here:

http://www.laushaus-dot-com/tesla/

His coil seems to perform better than we would expect due to SLTR 
things.  We never have been able to really understand it before.  We "sort 
of know why", but it is scary to go experimenting in the SLTR region since 
NST currents and stresses are enormous.  Now days, you and I have some NSTs 
just laying around, so maybe some testing is in order...

BTW - For those that have not been on the list forever ;-))  "SLTR" = 
"saturating larger than resonant".  We know that with really high primary 
cap values, and perhaps with high input voltages, that the currents in a 
NST can get so high that the shunts "saturate" and basically fall out of 
the circuit allowing very high output currents.  This condition can really 
get a lot of power out of an NST and charge abnormally high capacitor 
sizes.  Down side is things are very stressed and at the edge of control so 
it is very hard to play with this.  Pretty uncharted territory...  Gary 
Lau's coil seems to work fairly well in this region but not to much else is 
known.

Cheers,

         Terry
