Improved State Selection For Hydrogen MasersImproved selection system for hydrogen maser helps exclude hydrogen atoms from storage bulb in undesired quantum states not contributing to amplification/oscillation process. Atoms in undesired states limit stability of maser by reducing storage lifetime of atoms in desired state, reducing output power, and colliding with atoms in desired state under circumstances that causing systematic shifts in frequency.
