Magnus - When I scan/read the 1984 IEEE document, “Lifetime and Reliability of Rubidium Discharge Lamps for Use in Atomic Frequency Standards” by Aerospace Corp., Efraton-Ball, and EG&G. https://ieeexplore.ieee.org/document/1537723/ The failure of the rubidium lamps used on early NAVSTAR satellites, was the reason for in-depth studies of the Rb lamp, its lifetime and failure mechanism.
