How many gaps were you using originally in the RQ gap, what were
their spacing, and how many did you actually use of the 30 new 9
mil spaced gaps?  

Thanks for your interesting report.

 	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
 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
 Another day in the life of a college coiler.
