Permeability Measurements of Magnetic Shielding for the SNS nEDM Experiment
ORAL
Abstract
Because CP violation of the neutron electric dipole moment (nEDM) could explain the baryon asymmetry of the universe, the experimental search for an nEDM is a high priority in cosmology and nuclear physics. In order to maximize the sensitivity of such experiments, they must be conducted in a stable magnetic environment, which requires extensive magnetic shielding. A prototype magnetic shield is being constructed at UK to model the full shield in the SNS nEDM experiment. The B-H curve of mu-metal was analyzed by measuring the inductance of a transformer with a mu-metal core vs an air core of the same geometry. The resulting permeability will be used to model degaussing and performance of the prototype shield.-
