Abstract
We report on studies completed in the design of a dual atom beam accelerometer/ gyroscope.
As demonstrated in [1,2], two opposing beam atom interferometers can distinguish between
linear and rotational motion. Our design uses the transit time of slow moving atoms that
originate from a 2D MOT through continuous Raman laser fields as the ‘pulse’ of light’ for light pulse interferometry. Using both Monte Carlo methods as well as analytic expressions, we explore the effects of longitudinal and transverse velocity spread, laser beam profile and scattered light on the contrast of the interference fringe. We present the status of the
construction of our prototype (Fig. 1). We present measurements of narrow velocity profiles
from our source and demonstrate Raman spectroscopy using a cold continuous source.
