this is interesting, but wouldn't the air need to be filtered of all
moisture? maybe the compressed cylinder would be a good starting point.
does the book show the annular ring directly around the anode or spaced
away from it? would the placing of the trigger ring be something that
would have adjusted for the best performance with whatever triggering
voltages or currents your using?
good stuff,
