You all surely know the problem, that if a standard Nixie tube is off for a longer time, say 1 hour, and switched on at night, it takes some time (0.1 ... 3 seconds) until the glowing comes up. Does anyone know a method to speed up the ignition in this condition? I have found out that: - higher voltage does not make a change - higher target current does not make a change - slew rate of the switch (means a sharp pulse) does not make a change It looks like nothing helps to make it glow immediately. All the best Dieter

I don't think there would be any need to add helium, hydrogen, or even krypton-85 to *indicator* tubes. Helium and hydrogen no, but some 5092s had Kr85 for rapid ionization for multiplexed use.
