Measurement of the neutron incoherent scattering length of Hg using stored ultracold neutrons

C. Abel, K. Bodek, E. Chanel +35

We present the first direct measurement of the neutron incoherent scattering length of Hg. The measurement was performed with the Ramsey apparatus of the neutron electric…

Generating a highly uniform magnetic field inside the magnetically shielded room of the n2EDM experiment

C. Abel, N. J. Ayres, G. Ban +63

We present a coil system designed to generate a highly uniform magnetic field for the n2EDM experiment at the Paul Scherrer Institute. It consists of a main coil and a set of…

A large 'Active Magnetic Shield' for a high-precision experiment

C. Abel, N. J. Ayres, G. Ban +48

We present a novel Active Magnetic Shield (AMS), designed and implemented for the n2EDM experiment at the Paul Scherrer Institute. The experiment will perform a high-sensitivity se…

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…

Search for ultralight axion dark matter in a side-band analysis of a 199Hg free-spin precession signal

C. Abel, N. J. Ayres, G. Ban +35

Ultra-low-mass axions are a viable dark matter candidate and may form a coherently oscillating classical field. Nuclear spins in experiments on Earth might couple to this oscillati…

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…
