Pharao: a Space Clock with Cold Cesium Atoms
We describe a cold atom clock designed for operating in micrograv@, the PHARAO project. Preliminary resulfs have a W y been obtained on earth and the prototJpe wil l be Wed in the reduced g r a v e of aircrajl parabolic flights in the beginning of 1997. The PHARAO prototype i s an extension of the work done at the BNM-LPTF on a cesium atomic fountain, which presents a resonance linewidth of 700...
متن کاملParcs Magnetic Field Measurement: Low Frequency Majorana Transitions and Magnetic Field Inhomogeneity
1 Contribution of NIST, an agency of the US government; not subject to copyright in the United States Abstract Knowledge of the magnetic field is required to determine the quadratic Zeeman bias of a cesium frequency standard. The small magnetic fields (C-field) used in PARCS (PARCS is the primary atomic reference clock in space project), may have sufficient inhomogeneity that it is not practica...
متن کاملA cesium beam atomic clock using laser optical pumping. Preliminary tests
2014 A passive microwave cesium beam resonator utilizing optical pumping with a C.W. narrowband tunable laser (here, a GaAs laser) has been realized. A population difference between the levels of the ground state hyperfine transition of 133Cs (at 9 192.631... MHz) is achieved by optical pumping with the GaAs laser; the microwave resonance is detected through a change in the intensity of the flu...
متن کاملA general cold atomic and molecular beam source
We demonstrate and characterize a high-flux beam source for cold, slow atoms or molecules. The desired species is vaporized using laser ablation, then cooled by thermalization in a cryogenic cell of buffer gas. The beam is formed by particles exiting a hole in the buffer gas cell. We characterize the properties of the beam (flux, forward velocity, temperature) for both an atom (Na) and a molecu...
