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…
Time-of-flight spectroscopy of ultracold neutrons at the PSI UCN source
G. Bison, W. Chen, P. -J. Chiu +9
The ultracold neutron (UCN) source at the Paul Scherrer Institute (PSI) provides high intensities of storable neutrons for fundamental physics experiments. The neutron velocity spe…
