What voltage should a 5000 Joule capacitor bank be for a TEA nitrogen laser be?
I am building a TEA Nitrogen laser and I will be using two 5000 Joule capacitor banks for the two capacitors. I am wondering what voltage should the two cap banks be at for the laser. All help is greatly appriciated.

I don't recall how many farads you have.
Then you calc the voltage.
Energy = Capacitance × Voltage2 / 2
V = square root ( 10,000 / C )

How many Farads will be determined by how many Volts I need for it to work.

That's going to depend on your laser tests isn't it ? Its related to the sparkgap dimensions.
You can't HAVE "5000J" banks, without knowing the working voltage.

There are two upper bounds on voltage.
- The distance of Jhon's gap of about 1 to 3 millimeters.
- The insulation you use in your capacitor
Now the Kyerohtaron TEA N2 Laser uses 4000 V so,C = E*2/V2 = 5000 × 2 / ( 4000 × 4000 ) in FARADS
C = 625 uF................ Tell us John how large a foil cap is that ??
Will it fit in a garage ??

I honestly don't know. I would like to use homeade capacitors, but I don't know the specifications for them so that I can build the two capacitor banks using them. I have decided that I will use around 4500V.
