  We demonstrate a technique for producing a cold pulsed beam of atoms by
transferring a cloud of atoms trapped in a three dimensional magneto-optic trap
(MOT). The MOT is loaded by heating a getter source of Rb atoms. We show that
it is advantageous to transfer with two beams (with a small angle between them)
compared to a single beam, because the atoms stop interacting with the beams in
the two-beam technique, which results in a Gaussian velocity distribution. The
atoms are further cooled in optical molasses by turning off the MOT magnetic
field before the transfer beams are turned on.
