Re: Big bangs from MOT

Hi Julian, All,
The biggest flaw I can see is that Marx gens do put out a big kick (HV and
high Joules), but, Marx gens (your circuit diagram isnīt quite correct for a
real Marx gen) are not designed to produce a constant supply of voltage. They
need charge time, so they are of no use in a TC circuit, unless you want a
really sllllooooow BPS rate.
What you may have meant to say was a "Marx gen" on a semiconductor basis. I.e.
a voltage multiplier. Problem would be getting the big (in uF and volts) caps
needed.

What do you think of this for a design that allows high voltage bangs
when you only have a low voltage supply transformer.
Many coils employ multi gap static spark gaps. So build a marks
generator. String a few largish capacitors up in series with
single static spark gaps between the caps (Caps must be same
type). Then connect each capacitor up to the supply with chokes.

2KV supply - MOT. No problems with series transformers and insulation
breakdown. For higher voltage add more caps, for higher power add
transformers wired in parallel.
When spark gaps fire capacitors are connected in series to generate a
6KV pulse between points A and B. (Assuming spark gaps fire at 2KV)
Connect tesla primary across points A and B, and tune up in the normal
way.
Martin: I havn't tried your capacitors out in this configuration, yet -
perhaps 0.3uF it a bit big for a tesla coil.
