The Russians regularely used thyratrons, both cold cathode types and those

Has anyone done/seen Dekatrons used in conjunction with thyratrons?
I just happen to have some thyratrons which I bought as spares for a Russian
Geiger counter I was repairing (fault was actually a gas voltage regulator
tube.) They were actually being sold as decimal indicators for Nixie cloc
My bedside nixie clock was built with six IN-14's. It currently has 44,562
hours of operation, and the nixies show no sign of dimming. That time is

The lifespan of a nixie is not a precise science - end of life may be
considered as when luminosity drops by 50% (Weston), sputtering destroys a
cathode, cathode poisoning renders a glyph unreadable (though this may be
reversible), mechanical damage etc.
I was wondering about the luminosity and
