Search for an interaction mediated by axion-like particles with ultracold neutrons at the PSI
N. J. Ayres, G. Bison, K. Bodek +44
We report on a search for a new, short-range, spin-dependent interaction using a modified version of the experimental apparatus used to measure the permanent neutron electric dipol…
Characterization of ultracold neutron production in thin solid deuterium films at the PSI Ultracold Neutron source
G. Bison, B. Blau, W. Chen +13
We determined the ultracold neutron (UCN) production rate by superthermal conversion in the solid deuterium (sD) moderator of the UCN source at the Paul Scherrer Institute (PSI…
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…
Measurement of the permanent electric dipole moment of the neutron
C. Abel, S. Afach, N. J. Ayres +81
We present the result of an experiment to measure the electric dipole moment (EDM) of the neutron at the Paul Scherrer Institute using Ramsey's method of separated oscillating magn…
Data blinding for the nEDM experiment at PSI
N. J. Ayres, G. Ban, G. Bison +42
Psychological bias towards, or away from, a prior measurement or a theory prediction is an intrinsic threat to any data analysis. While various methods can be used to avoid the bia…
Optically Pumped Cs Magnetometers Enabling a High-Sensitivity Search for the Neutron Electric Dipole Moment
C. Abel, S. Afach, N. J. Ayres +57
An array of sixteen laser-pumped scalar Cs magnetometers was part of the neutron electric dipole moment (nEDM) experiment taking data at the Paul Scherrer Institute in 2015 and 201…
nEDM experiment at PSI: data-taking strategy and sensitivity of the dataset
C. Abel, N. J. Ayres, G. Ban +40
We report on the strategy used to optimize the sensitivity of our search for a neutron electric dipole moment at the Paul Scherrer Institute. Measurements were made upon ultracold…
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…
The n2EDM experiment at the Paul Scherrer Institute
C. Abel, N. J. Ayres, G. Ban +45
We present the new spectrometer for the neutron electric dipole moment (nEDM) search at the Paul Scherrer Institute (PSI), called n2EDM. The setup is at room temperature in vacuum…
Statistical sensitivity of the nEDM apparatus at PSI to neutron mirror-neutron oscillations
C. Abel, N. Ayres, G. Bison +33
The neutron and its hypothetical mirror counterpart, a sterile state degenerate in mass, could spontaneously mix in a process much faster than the neutron -decay. Two groups hav…
Solid deuterium surface degradation at ultracold neutron sources
A. Anghel, T. L. Bailey, G. Bison +27
Solid deuterium (sD_2) is used as an efficient converter to produce ultracold neutrons (UCN). It is known that the sD_2 must be sufficiently cold, of high purity and mostly in its…
Search for axion-like dark matter through nuclear spin precession in electric and magnetic fields
C. Abel, N. J. Ayres, G. Ban +45
We report on a search for ultra-low-mass axion-like dark matter by analysing the ratio of the spin-precession frequencies of stored ultracold neutrons and Hg atoms for an a…
