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…

The PanEDM Neutron Electric Dipole Moment Experiment at the ILL

David Wurm, Douglas H. Beck, Tim Chupp +24

The neutron's permanent electric dipole moment is constrained to below (90% C.L.) [ arXiv:hep-ex/0602020, arXiv:1509.04411 ], by experiments usi…

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…

Neutron lifetime measurements with the big gravitational trap for ultracold neutrons

A. P. Serebrov, E . A. Kolomensky, A. K. Fomin +14

Neutron lifetime is one of the most important physical constants which determines parameters of the weak interaction and predictions of primordial nucleosynthesis theory. There rem…

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…

Neutron lifetime measurements and effective spectral cleaning with an ultracold neutron trap using a vertical Halbach octupole permanent magnet array

K. K. H. Leung, P. Geltenbort, S. Ivanov +2

Ultracold neutron (UCN) storage measurements were made in a trap constructed from a 1.3 T Halbach Octupole PErmanent (HOPE) magnet array aligned vertically, using the TES-port of t…
