Re: [TCML] 1 Mhz ,1 kw
I think a PT is exactly what you want. You could parallel a couple 15/60
NST's or even remove shunts out of a 60mA NST, but that is the last
option you would want to go after. If you can find a decent PT about
12kV-15kV then all the better. Your bps range is good and can deliver
580-675 W across the gap (energy * bps) with say a 15kV, 120mA source.
Regarding the cap, I recommend P/N 942C20P15K-F from Cornell Dubilier.
Two options with the above cap value for 10nF:
For 30KV, 1 string of 15 caps.
For 60kV, 2 strings of 30 caps.
Both are 10nF, and of course the 60kV is ideal. I think the 30kV cap
bank would be fine for this.
Dex, if you do go building a 1MHz 1KW coil, you might also want to build
a normal 1000T secondary using 24 AWG with the same geometry and a
primary to suit. Only if funds allow it of course. But that might be a
great means of comparing coils using the same external components (gap,
bps, input, etc.).
Take care,
Bart

Thanks for the photo.
I think power source for the coil I want to build is a potential transformer.
And I'm thinking of use ASRG with 300-400 PPS.Cp about 10 nF.
Still thinking of how to realize good 40 kV capacitor bank for the purpose.

For myself, I have built
something close, 750kHz coil. It was one of these small little coils
with a lot of losses and problems. The only image I have of it is here
(it just happened to get into the photo). It's the little coil on the
right side of the picture. It was built for a buddy down the street
(little 7500V, 20mA NST coil).
