Measurement of a false electric dipole moment signal from Hg atoms exposed to an inhomogeneous magnetic field
S. Afach, C. A. Baker, G. Ban +46
We report on the measurement of a Larmor frequency shift proportional to the electric-field strength for atoms contained in a volume permeated with aligned magneti…
Magnetic field uniformity in neutron electric dipole moment experiments
C. Abel, N. Ayres, T. Baker +53
Magnetic field uniformity is of the utmost importance in experiments to measure the electric dipole moment of the neutron. A general parametrization of the magnetic field in terms…
Mapping of the magnetic field to correct systematic effects in a neutron electric dipole moment experiment
C. Abel, N. J. Ayres, G. Ban +50
Experiments dedicated to the measurement of the electric dipole moment of the neutron require outstanding control of the magnetic field uniformity. The neutron electric dipole mome…
A highly stable atomic vector magnetometer based on free spin precession
S. Afach, G. Ban, G. Bison +31
We present a magnetometer based on optically pumped Cs atoms that measures the magnitude and direction of a 1 T magnetic field. Multiple circularly polarized laser beams were u…
Demonstration of sensitivity increase in mercury free-spin-precession magnetometers due to laser-based readout for neutron electric dipole moment searches
G. Ban, G. Bison, K. Bodek +31
We report on a laser based Hg co-magnetometer deployed in an experiment searching for a permanent electric dipole moment of the neutron. We demonstrate a more than five tim…
Observation of gravitationally induced vertical striation of polarized ultracold neutrons by spin-echo spectroscopy
S. Afach, N. J. Ayres, G. Ban +45
We describe a spin-echo method for ultracold neutrons (UCNs) confined in a precession chamber and exposed to a magnetic field. We have demonstrated that the an…
