Yes, right, but it works for tubes like B-5025 series, since they are
mercury-free and the getter mirror is on the back of the tube.

Flashes getters aren't good for nixie tubes because barium mirror
exchange mercury vapours to another gases. That's why.

Thats exactly what I mean, I will use flashed getter for testing - I
will disassemble some old TV tube as Ron suggested. But I want to use
right getter later..
Do You have any info about your progress on your site?

Hi folks,
the only tube with a flashed getter I know of is the XN-1:
http://www.tube-tester.com/sites/nixie/data/XN1/XN1.htm
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..
