RE: [TCML] 5kv plane gap size

["Jim Mora" <wavetuner@xxxxxxxxx>]

Hi Scot,

A bit off topic; but, I have a 240uf,5kv Maxwell discharge cap. The concept
is equal to our other projects.

I want to blow some wire and maybe launch some hard disk plates. It really
packs a very respectful wallop.

The brass dowel faces are 2" in diameter. This demands some serious respect.
After a full discharge, a few moments later it discharges yet again to
ground with the sound of a >cherry bomb! It should be very impressive when
the gap breaks down now that I know the approximant spacing!

I also am experimenting making an HV supply with a Panasonic microwave oven
inverter and a multiplier circuit.

Thanks Much,
Jim Mora

Hey Jim...
I had to bring out the "book" ( Machinery's handbook # 24and some upper 
end old collage electronics texts) to do some research but considering 
your altitude, the so called average would be about 40 - 60 thou 
depending on humidity ( 95 - 40%) respectively) on flat electrodes of 
approximately 3/8" and larger dia flat faced surfaces...  seems that 
less than 3/8" dia has a tendency to behaive more like rounded or "semi 
hemispherical" at 5KV...

what are you building??  and what size electrodes are you using??  are 
you looking for continious arc after conduction or something that is 
"quenchable" ??

interested in your design...
