Re: Pressure adjustments for smaller tubes
Tom,
very good points. The best example I hear of time and time again is of
people doing the letter "i" . Everyone has a tendency to "make the letter
look better" by making the dot on the top a seperate piece rather than having
a transition from the body of the letter to the dot. The dot might have 6
inches of glass in it when it is done seperatly. If it's pumped red, and
filled to "normal" pressure it dies in 6 months.
As for "compression" of the arc stream in real high pressure tubes, I'm
guessing that it occurs because of a combination of 1) path of least
resistance / shortest path, combined with 2) tangentially off this path
between electrodes energized parts flying around don't need to move far
before they hit somthing else; in a normal pressure tube they would travel
further before things collide which would spread out the arc stream ( ? hey,
us ME's need a lot of models for stuff like this cuz we really don't
understand electricity. Any real EE's would be welcome to chime in now).
