Achieving ultra-low and -uniform residual magnetic fields in a very large magnetically shielded room for fundamental physics experiments
N. J. Ayres, G. Ban, G. Bison +47
High-precision searches for an electric dipole moment of the neutron (nEDM) require stable and uniform magnetic field environments. We present the recent achievements of degaussing…
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…
The `n2EDM MSR' -- a very large magnetically shielded room with an exceptional performance for fundamental physics measurements
N. J. Ayres, G. Ban, G. Bison +41
We present the magnetically shielded room (MSR) for the n2EDM experiment at the Paul Scherrer Institute which features an interior cubic volume with each side of length 2.92m, thus…
Improved search for neutron to mirror-neutron oscillations in the presence of mirror magnetic fields with a dedicated apparatus at the PSI UCN source
N. J. Ayres, Z. Berezhiani, R. Biondi +22
While the international nEDM collaboration at the Paul Scherrer Institut (PSI) took data in 2017 that covered a considerable fraction of the parameter space of claimed potential si…
