Loaded microwave cavity for compact vapor-cell clocks
Michele Gozzelino, Salvatore Micalizio, Claudio E. Calosso +3
Vapor-cell devices based on microwave interrogation provide a stable frequency reference with a compact and robust setup. Further miniaturization must focus on optimizing the physi…
Reducing cavity-pulling shift in Ramsey-operated compact clocks
Michele Gozzelino, Salvatore Micalizio, Filippo Levi +2
We describe a method to stabilize the amplitude of the interrogating microwave field in compact atomic clocks working in a Ramsey approach. In this technique, we take advantage of…
Phase-shift in vapor cell and compact cold-atom frequency standards
Aldo Godone, Salvatore Micalizio
We report on a theoretical analysis of the phase-shift in compact atomic clocks working either with cold or thermal atoms. It is well known that in a microwave cavity with electrom…
Black Body Radiation Shift of the 133Cs Hyperfine Transition Frequency
S. Micalizio, A. Godone, D. Calonico +2
We report the theoretical evaluations of the static scalar polarizability of the 133Cs ground state and of the black body radiation shift induced on the transition frequency betwee…
Measurement of the Blackbody Radiation Shift of the 133Cs Hyperfine Transition in an Atomic Fountain
F. Levi, D. Calonico, L. Lorini +2
We used a Cs atomic fountain frequency standard to measure the Stark shift on the ground state hyperfine transiton frequency in cesium (9.2 GHz) due to the electric field generated…
