Electrically determining xenon tube polarity
(1/4) > >>
The Lightning Stalker:
Say I have a xenon tube tucked up in an inaccessible place where I cannot see it or safely remove it. Does anyone know if xenon tubes like the kind found in camera flashes display a polarity dependent nonlinear characteristic that can be seen for example on an oscilloscope? thanks
soldar:
A "polarity dependent nonlinear characteristic"? The short answer is "no".

The flash tube will be powered by a DC, polarized capacitor.

What are you trying to do?

Have a look at https://en.wikipedia.org/wiki/Flashtube
mikeselectricstuff:
Afaik the differences on electrodes are to do with rates of erosion over time, so seems unlikely you could measure it remotely. Worst case it just doesn't last as long
The Lightning Stalker:
Sorry I should have made clear that the idea is to determine the polarity of said tube electrically when visual identification is not possible.

Yes we understand that. Sorry so far no one knows of a way to do it.

I think it may trigger at a lower voltage when given the correct polarity, but I could be wrong.
