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…
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…
A comparison of two magnetic ultra-cold neutron trapping concepts using a Halbach-octupole array
K. Leung, S. Ivanov, F. Martin +3
This paper describes a new magnetic trap for ultra-cold neutrons (UCNs) made from a 1.2 m long Halbach-octupole array of permanent magnets with an inner bore radius of 47 mm combin…
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…
