Re: A real quarter wave TC ?

Hi, again
Yes, the correct value is 35nf. I will be using an 1,800 rpm, 4 pole, SRSG. I made a serious mistake in my first post. My frequency to wavelength conversion was faulty and therefore the secondary calculations were wrong. I have made the necessary new calculations and will probably throw the unit together over the weekend. The primary (with capacitor) and secondary (without a topload) will both be resonant at about 210khz and the wire length of the secondary will be 1/4 wave at 210khz. Will post results, hopefully next week.

Hi Bart,

Did you calculate the resonant C for his NST.  9000V@120ma ??

Unless I made a mistake, I believe it is 35 nf. He is planning on a 35 nf cap using a SRSG (he said 4 pole rotor but didn't say whether he is running at 1800 or 3600 rpm.

The NST will be fine
charging the cap. You could do 120 bps
efficiently and even 240 bps well.
