Neon with a small amount of Argon (maybe 5%) and possibly a trace of Mercury (nearly all later tubes have Hg doping - it almost eliminates sputtering and thus drastically improves the life of the tube). Pressure is between 5 & 30 Torr (about 1/25th of an atmosphere). HTH Nick -- You received this message because you are subscribed to the Google Groups "neonixie-l" group.
