A low velocity, low temperature beam of atoms is produced
from a two-dimensional magneto-optic trap known as an atomic
funnel. The funnel provides simultaneous spatial and velocity
compression of atoms and will provide a source for a three-grating
atomic interferometer. Rubidium atoms from an oven are slowed
by chirped cooling and loaded into the trap. Atoms are ejected from
the trap using frequency offsets in optical molasses. The resultant
beam has a controllable velocity in the range of 3 to 10 m/s with
temperatures of order 500 ��K. / Graduation date: 1996
