Re: Spark Gap Gasses Experiment


Good luck on the argon gap! For significantly better quenching, and
perhaps greater cooling efficiency, hydrogen gas may be the best choice
of fill gas. 

Also, if you plan to seal the gap, you may be able to get by with just
air, since the most of the initial oxygen in the entrapped air will
fairly quickly combine with the copper, and further oxidation should
then stop. In the early days of spark radio, this approach was used in
sealed quenching sparkgaps with excellent success.
