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 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…

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…

Johnson-Nyquist Noise Effects in Neutron Electric-Dipole-Moment Experiments

N. J. Ayres, G. Ban, G. Bison +37

Magnetic Johnson-Nyquist noise (JNN) originating from metal electrodes, used to create a static electric field in neutron electric-dipole-moment (nEDM) experiments, may limit the s…

The design of the n2EDM experiment

N. J. Ayres, G. Ban, L. Bienstman +58

We present the design of a next-generation experiment, n2EDM, currently under construction at the ultracold neutron source at the Paul Scherrer Institute (PSI) with the aim of carr…
