This paper presents a setup capable of producing a high-flux continuous beamof cold rubidium atoms for cavity QED experiments in the regime of strongcoupling. A 2 $D^+$ MOT, loaded by rubidium getters in a dry film coated vaporcell, fed a secondary moving-molasses MOT (MM-MOT) at a rate of 1.5 x $10^{10}$atoms/sec. The MM-MOT provided a continuous beam with tunable velocity. Thisbeam was then directed through the waist of a 280 $\mu$m cavity resulting in aRabi splitting of more than +/- 10 MHz. The presence of sufficient number ofatoms in the cavity mode also enabled splitting in the polarizationperpendicular to the input. The cavity was in the strong coupling regime, withparameters (g, $\kappa$, $\gamma$)/2$\pi$ equal to (7, 3, 6)/ 2$\pi$ MHz.
