RE: X-rays from light bulbs/Tesla Coils !!!
Fr. Tom,
We are probably seeing gas glowing as it persists for a moment after the
power is cut. Can't tell if it has volume since the green glow is only
produced when running at higher powers where we need to stand back (I'll use
binoculars or a telescope on the next run). We'll hold off using the bulbs
till we get a chance to verify the absence (or presence) of x-rays via
instrumentation.
Thanks,
Brian Basura

Don't confuse glowing gases with glowing glass. The former
indicates the presence of a gas (argon/nitrogen, etc) and
the glowing gas has a VOLUME. On the other hand, if it is
just the inside surface of the glass that is glowing,
and there is no volume to the glow, (just a surface phenomenon),
then you probably have x-rays.
The presence of streamers inside the glass bulb *usually*
indicates the presence of gas.
