Original poster: "Dr. Resonance" <resonance@xxxxxxxxxx> from physics:Voltage across an inductor is produced by L x dI/dt, so the larger the inductance the better which means a larger radius (dia.) of inductor as the inductance goes up as the square of the radius and also as the square of the number of turns.
There is a limit though as you begin to hit a "resistance point" at which more turns will decrease not increase performance. We usually keep ours at 1,400 turns --- other experimenters have measured best performance at 950 turns using a 6.5 inch OD PVC tube as the coilform.

Original poster: Adriano.Mollica@xxxxxxxxxxx hello to everyone, i'm trying to understand some things: 1) what parameter influence more the lenght of the sparks?2) if i have a spintermetic TC and i like to pilot it by a solid state driver, what should i do?3) does bigger TC makes always longest sparks, with the same caps and NST? thanks a lot , bye bye
