A Revised Experimental Upper Limit on the Electric Dipole Moment of the Neutron
J. M. Pendlebury, S. Afach, N. J. Ayres +47
We present for the first time a detailed and comprehensive analysis of the experimental results that set the current world sensitivity limit on the magnitude of the electric dipole…
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 us…
Ultracold neutron production and up-scattering in superfluid helium between 1.1 K and 2.4 K
K. K. H. Leung, S. Ivanov, F. M. Piegsa +2
Ultracold neutrons (UCNs) were produced in a 4 liter volume of superfluid helium using the PF1B cold neutron beam facility at the Institut Laue-Langevin and then extracted to a det…
Gravitational Depolarization of Ultracold Neutrons: Comparison with Data
S. Afach, N. J. Ayres, C. A. Baker +47
We compare the expected effects of so-called gravitationally enhanced depolarization of ultracold neutrons to measurements carried out in a spin-precession chamber exposed to a var…
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 ana…
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…
A device for simultaneous spin analysis of ultracold neutrons
S. Afach, G. Ban, G. Bison +37
We report on the design and first tests of a device allowing for measurement of ultracold neutrons polarisation by means of the simultaneous analysis of the two spin components. Th…
