Abstract

One embodiment of the invention includes an alkali beam cell system that comprises a reversible alkali beam cell. The reversible alkali beam cell includes a first chamber configured as a reservoir chamber that is configured to evaporate an alkali metal during a first time period and as a detection chamber that is configured to collect the evaporated alkali metal during a second time period. The reversible alkali beam cell also includes a second chamber configured as the detection chamber during the first time period and as the reservoir chamber during the second time period. The reversible alkali beam cell further includes an aperture interconnecting the first and second chambers and through which the alkali metal is allowed to diffuse.
