Oral Presentation

A robotic 3D mapper has been developed to characterize the magnetic field in the shielded environment of the nEDM experiment at Los Alamos National Lab. The mapper allows for movement within a cylindrical volume and probes the magnetic field with a fluxgate magnetometer. Analysis of mapper data will be used to determine the effectiveness of both magnetic shielding methods and holding field...

Oral Presentation

The n2EDM experiment at the Paul Scherrer Institute (PSI) aims to reach a neutron electric-dipole-moment (nEDM) sensitivity of $1\times10^{-27}~e\cdot\mathrm{cm}$. At this sensitivity, magnetic-field nonuniformities must be tightly controlled. In particular, odd-order harmonic modes contribute to a motional false EDM through the $^{199}\mathrm{Hg}$ co-magnetometer. These modes must be...
