Re: UV Detection methods was Ultraviolet light from brush discharge.
Hi all,
Probably a little off topic, but I just have to throw in my observations

I was testing my coil using a static gap in a peice of PVC pipe (sorta like
an RQ gap), I had the gap just sitting on the carpet sideways (yeah, I know,
BIG fire hazzard) with an ac fan blowing through the gap away from me. I was
just running the coil for short runs in the dark when I noticed that the arc
from the gap hardly lit up the room, except for white papers on the wall,
which glew (is that a word) bright purple - that is to be expected, but the
odd thing was, that after I turned off the coil there was a glowing violet
plume on the carpet in the direction that the fan was blowing (through the
back of the gap, like a jet engine exhaust). It was like there was
glow-in-the-dark material in the carpet, and it lasted clearly vissible for
at least 5 secconds before fading away. Has anyone ever heard of unlikly
materials aquiring(storing) UV energy like this and slowly releasing
it? -thought it was weird anyway.
