Hi folks,
the only tube with a flashed getter I know of is the XN-1:

To be honest: I will not use getters at the moment. There is so much
glasswork to figure out for me, that is the part that I will focus on in
the next months. :-)

Hi Dylan,
flashed getters are not used in nixies (I havent seen it at least),
just some VFD tube use flashed getters. Flashed getters leave a
coating on a glass envelope of the tube - we don't want that. I think
that kind of getter needs only initial activation by heat which could
be done by induction heating as well as in the case of flashed
getters. Look to IN-14 nixie, there is exactly the same pellet.
The only matter to solve will be attaching the pellet to a wire, but I
think that will be possible to do by spot welding - inspired by IN-14.
Thanks,
Dalibor

Hey Dalibor and others-
I don't feel that these are the right getters for nixie tubes.
The literature lists them as thermally active- they only absorb
if you put them somewhere hot.
Many styles of getters are made this way; most tubes do run
quite hot, beacuse of the filaments..
There isn't anywhere in a nixie tube that is constantly
100C-200C. (That's part of the magic of nixies, of course)
You really want some flashed barium getters; they absorb gasses
at any temperature.

Hello guys,
I've got an offer on getters, tech info attached.. the price
is approx. 5pcs/1 eur. Is anyone interested in it? I will
place an order in several weeks, I may send some pieces sealed
in argon filled tube..
