Subject: 30 9 mil gaps, great quenching

	I have bin using a RQG with forced air and have bin getting 3rd notch 
quenches, Then I switched to a RQG with a vacuum cleaner pulling air through 
it.  This gave me 2nd notch quenching.  At this point I was getting 33" 
streamers.  I read some of Terry's writing and decided to build a static gap 
that would have 30 gaps that were 9 mils each.  So I built it and connected it
into my primary circuit.  Then I stepped back 4 feet and flipped the switch.

	A huge explosion of sparks came off of the secondary nearly hitting me 
in the arm.  After I moved away another 4 feet and checked my pulse I 
turned it back on.  It was putting out nice 39" streamers on 15KV/60ma NST.  
I checked my scope and noted that it quenched on the first notch every time.  
I was also getting some corona from my strike rails so I replaced the wire 
with copper tubing and it went away.  At this point I was low on time so I 
didn't have a chance to change the coupling.  Ow well, that will be tomorrow's

Another day in the life of a college coiler.
