In this sub-project the behaviour of different mu-metal test samples will be investigated during their demagnetization. To this end, we will set up an experimental equipment to demagnetize complex mu-metal parts. Using this equipment, we will optimize the demagnetization process for these test samples. We will perform test series to measure the residual magnetism and the gradients on the surfaces of the test samples as well as their shielding factors. We will investigate magnetically all parts essential for the prototype. To this end a midi SQUID System will be set up to perform vector measurements near the surface of samples with narrow geometries. A midi robot will be developed to perform these investigations with a high reproducibility.
