It is clearly important to pursue atomic standards for quantities like electromagnetic fields, time, length, and gravity We have recently shown using Rydberg states that Rb atoms in a vapor cell can serve as a practical, compact standard for microwave electric field strength Here we demonstrate fo collisions of the atomic vapor with the walls The rubidium magnetometers described here normally employ a fairly high pressure buffer gas (3 cm Hg or higher) of neon and a filter is needed to pass the resonance radiation at X 7948 and reject X 7800 An interference filter has been developed for this purpose* whichPrinciples of Operation of the Rubidium Vapor Inside the atomic resonator there is a rubidium vapour cell The atoms are kept in a gaseous state at high temperature In order to initiate the resonance, the atoms of the cell are excited to a higher state by the light of a rubidium discharge lamp located in one end of the atomic resonatorESA How the Galileo atomic clocks work
