Heavier noble gases such as xenon and argon can reduce the run-in period for vacuum tubes and in particular flame detector tubes. The tubes can be filled with a run-in gas and then run-in. The run-in gas can then be exchanged for an end gas, such as neon, and the tube sealed. A final conditioning step of running in the tube with the end gas can further smooth the tube's anode and cathode to thereby improve performance and operating life.
