Summary form only given. We have constructed a prototype of an /sup 87/Rb fountain clock. We collect 10/sup 10/ /sup 87/Rb atoms in a vapor cell magneto-optic trap (MOT). The laser system for trapping and cooling is entirely solid state--a grating stabilized laser injects a separate slave laser for each of the six beams of the MOT. We launch the atoms by frequency shifting the three downward propagating laser beams and then increasing the detuning and gradually reducing the intensity of the slave lasers to adiabatically cool the atoms to low temperatures in the fountain.
