Description
The n2EDM experiment searches for the neutron electric dipole moment, which could help understand the baryon asymmetry of the universe. To allow for high precision measurements, an active magnetic shielding (AMS) and a magnetically shielded room (MSR) for passive shielding ensure a magnetically controlled volume.
Using the AMS coil system external magnetic fields can be compensated. The interplay between the AMS-generated fields and the mu-metal cube of the MSR is examined through COMSOL simulations. The poster discusses implementation and simulation methods and effects of the mu-metal cube on the AMS. The simulations also aim to find optimal positions for the AMS feedback sensors.
