Cold Atom Lab 2005-2007 Update
Abstract
The Cold Atom Research Laboratory at Hanscom AFB is investigating the fundamental physical limitations as well as the practicality of developing precision rotation sensors using the interference of alkali atoms in dilute gases. Atoms that have been laser cooled can have their momentum reduced to the point that they form a Bose-Einstein condensate, which can be 10 orders of magnitude more sensitive to rotation than a light-based interferometer. We have designed a 4-Wire Off Axis Microchip Ringtrap. A partially circular magnetic waveguide centered between all four wires is maintained by running counter-propagating current through either pair or all four wires. While the current is ramped down in the outer pair, the current is ramped up in the inner pair, so that the waveguide maintains its shape near the minimum where the atoms travel.
