Abstract

By utilizing the quadratic dependency of the interferometry phase on time, the Hannover Very Long Baseline Atom Interferometer facility (VLBAI) aims for sub nms−2 gravity measurement sensitivity. With its 10 m vertical baseline, the VLBAI offers promising prospects in testing fundamental physics at the interface between quantum mechanics and general relativity. Here we discuss the challenges imposed by controlling the VLBAI’s magnetic and gravitational environment and report on their effect on the device’s accuracy. Within the inner 8 m of the magnetic shield, residual magnetic field gradients expect to cause a bias acceleration of only 6 × 10−14 ms−2 while we evaluate the bias shift due to the facility’s non-linear gravity gradient to 2.6 nms−2. The model allows the VLBAI facility to be a reference to other mobile devices for calibration purposes with an uncertainty below the 10 nms−2 level.
