Is there any significant improvement is performance in placing the the 
spark gap in a vacuum?
I have a vacuum pump, and I was thinking of putting the SRSG in an airtight 
enclosure and sucking out the air. It would be easy enough to do, but I'm 
wondering if it would serve any practical purpose besides giving me the 
chance to put the unused pump to work...
