Abstract
We report on the design, construction, and characterization of a 10 m-long high-performance magnetic shield for very long baseline atom interferometry. We achieve residual fields below 4 nT and longitudinal inhomogeneities below 2.5 nT/m over 8 m along the longitudinal direction. Our modular design can be extended to longer baselines without compromising the shielding performance. Such a setup constrains biases associated with magnetic field gradients to the sub-pm/s2 level in atomic matterwave accelerometry with rubidium atoms and paves the way toward tests of the universality of free fall with atomic test masses beyond the 10-13 level.

N1 - The Hannover Very Long Baseline Atom Interferometry facility is a major research facility funded by the German Research Foundation (Deutsche Forschungsgemeinschaft, DFG). This work was supported by the Collaborative Research Centers 1128 “geo-Q” (Project No. A02) and 1227 “DQ-mat” (Project No. B07), and Germany’s Excellence Strategy within EXC-2123 “QuantumFrontiers” (Project No. 390837967). D.S. acknowledges funding from the German Federal Ministry of Education and Research (BMBF) through the funding program Photonics Research Germany (Contract No. 13N14875). E.W. acknowledges support from “Niedersächsisches Vorab” through the “Quantum- and Nano-Metrology (QUANOMET)” initiative (Project No. QT3 - 51170991). S.S. and P.F. acknowledge support from EXC-153 “Origin and Structure of the Universe” (Project No. 24799710). The work of C.U. was supported by the German Aerospace Center (DLR) with funds provided by the Federal Ministry for Economic Affairs and Energy (BMWi) due to an enactment of the German Bundestag under Grant Nos. DLR 50WM1556 and 50WM1956. E.W., D.T., E.M.R., and D.S. thank I. Fan and A. Schnabel for valuable insight at the beginning of the project. E.W. thanks T. Wendrich, K. M. Knaak, T. Hensel, and T. Rehmert for logistics help and the loan of measurement equipment.
