Abstract : The invention relates to an electro-chemical gas sensor for use in electron tubes comprising a crystalline body of BaO formed on a noninteracting (chemically and electrically) substrate and at least two electrodes. The change in conductivity of the barium oxide upon exposure to tube gases may be used to determine the type and quantity of gases contaminating the electron emitter and estimate changes in the emitter's work function or electron emission capability due to gas contamination.
