Abstract
A Bose-Einstein condensate is used as an atomic source for a high precision sensor. A spinor condensate of is released into free fall for up to 750 ms and probed with a Mach-Zehnder atom interferometer based on Bragg transitions. The Bragg interferometer simultaneously addresses the three magnetic states , facilitating a simultaneous measurement of the acceleration due to gravity with a 1000 run precision of and the magnetic field gradient to a precision of .
