Abstract: A method for measuring the population of atoms in a vapor cell comprises collecting a sample of atoms, applying radio frequency (RF) spectroscopy to the sample such that a first portion of the atoms are in an upper ground state and a second portion of the atoms are in a lower ground state, and applying light to the sample to produce a first fluorescence such that all atoms are left in the lower ground state. The method further comprises measuring a population of the atoms in the upper ground state based on the first fluorescence, applying an RF pulse to the sample to transfer the atoms in the lower ground state to the upper ground state, and applying light to the sample after the RF pulse is applied to produce a second fluorescence. A population of all the atoms in the sample is then measured based on the second fluorescence.

Abstract: A method of operating a cold atom clock to maintain a highly homogeneous microwave field is provided. The method includes: driving a subset of microwave feed lines to excite a microwave field in a resonator, while a power and a phase of at least one microwave feed line in the subset is held constant, and while the power or the phase of at least one other microwave feed line in the subset is changed; measuring a strength of the atomic transition excited by the microwave field; extracting a relative power and a relative phase between or among the subset of microwave feed lines by processing the strength of the atomic transitions excited by the microwave field measured in at least one auxiliary-measurement sequence; and determining if an adjustment to one or more of the microwave feed lines is needed to improve the homogeneity of the microwave field phase and amplitude.
