WebJun 7, 2024 · Optically pumped cesium beam atomic clocks use two hyperfine levels of cesium atoms ( F = 3, m F = 0> and F = 4, m F = 0>. In order to separate the other magneton levels from the two levels, we add a weak magnetic field, called C field. So we can reduce the influence of other magneton transitions.
WebA more symmetric beam reversal is possible with optical pumping methods, since all atoms may be included regardless of velocity and position within the beam. This should permit a better cancellation of cavity phase shifts. Angle tuning of the laser may result in velocity selection of atoms in the cesium beam, favoring slower velocity atoms, which orbimed iris wangWebMay 24, 2024 · In this paper, an efficient optical detection method in a magnetic state-selection Cs beam tube, using a DFB laser diode for counting the number of Cs atoms, is … ipod 5 price best buyWebSep 30, 2024 · Optical pumping is a conceivable mechanism for breaking the symmetry between equivalent spin configurations in TMDs.
