| Popis: | 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 |
