Abstract
A prototype of an Rb fountain clock is constructed. Rb atoms are collected in vapor cell magnetooptical trap and launched by frequency shift in a propagating laser beams. By increasing the detuning and by gradually reducing the intensity of the laser, the atoms are cooled adiabatically to 1.85 μK in the fountain. The atoms pass through 2 state preparation microwave cavities and then up and down through the clock cavity which is a waveguide coupled high-Q rectangular cavity. The results and the measurements of the cold collision shifts for Rb are presented.
