Re: [TCML] Still stuck at 36"

Thank you DC. Yes, "if" it were say a rod gap (flat face) of 3/4" 
diameter, about 13kVp. But, considering this is a pipe facing end to end 
(with roughly a 0.05" thickness of the pipe sheet thickness), the 
breakdown voltage should be roughly 8.3kV. Pressure does change the 
breakdown voltage and it appears the pressure has nearly doubled (which 
would put you at about 16.6kVp). This would be really cool to verify in 
a controlled test rig of sorts. I wonder if Jim Lux has any data on say 
breakdown at 2x pressure?

It would probably be beneficial to have the electrodes side by side 
rather than end to end. But a little difficult practically in a 
T-fitting chamber. I agree, a little adjustment now and then is no big 
deal considering the performance.

Thanks for the voltages.
