Subject: 30 9 mil gaps, great quenching
Hello,
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
adventure.
Another day in the life of a college coiler.
