The installation of a new generation of sources for ultracold neutrons (UCN) permits to improve the limits on one of the basic experiments in particle physics, the measurement of the electric dipole moment of the neutron dn [1] (EDM), by two Orders of magnitude to dn < 5 • 10~28 e-, because of increased particle density. Since current experiments are limited not only by statistics but also by systematic errors, new experiments have to be prepared by corresponding studies. It is known [3] that magnetic field based systematic effects play a central role while planning a new experiment. In this project we plan to realize a stable magnetic environment and to accomplish pre-studies that decisively guide the design of a large passive shielding.
