Opinions vary - some folks think the effective temperature of the ionized plasma is quite high, but since its mass and thermal conductivity is so low, it won't heat metal parts like getters very much. > You really want some flashed barium getters; they absorb gasses at any > temperature. I don't remember seeing barium getters in nixies. I have seen a few styles of pellet getters, but I'm guessing they're exotic types that work at room temperature and don't absorb neon or mercury. - John -- You received this message because you are subscribed to the Google Groups "neonixie-l" group.
