First light...Sort of
I started up my complete coil for the first time, with disappointing
results. Vital specs (from memory) are:
Power Supply: 15 kV NST
Tank Cap: 0.01 uF styrene
(0.04 uF 40mil dielectric x 4 in series)
Primary: 18 turns, 30 degree inverted cone
1/4" soft copper tubing, 1/4" spacing
Secondary: 4.125" dia. x 51" long secondary
Top Load: 4" x 32" toroid
Spark Gap: RQ style, 1/2" Cu tubing, 0.02" gaps, 10 gaps
First off, I know the secondary is way too long. It was the first
part of the project I assembled and I didn't know what I was doing
(not that I do now ;)
I tried several different tap locations on the primary, and managed to
get a few anemic purple sparks from the top load to the ceiling (about
1 foot).
The PVC tubing around the RQ gap buckled, causing most of the gaps to
short out, once this happened, no further sparks from the top load
were produced.
I'm going to build up a new gap, probably consisting of a series of Cu
tube section glued to a sheet of phenolic.
As a first attempt to improve performance, should I slice out a 20"
section of the secondary and use that?
