Abstract
A method of manufacturing a solid state sensor wherein a reactive compound of an alkali metal is tightly packed between a central electrode and a surrounding ion shield. A heating coil is wound about the outside of the shield. The ion shield is formed of a material that is deplete in ions of alkali metal and serves as a ion depletion boundry in the system.
