Realization and simulations of the new SPES Beam Cooler

A. Ruzzon, M. Maggiore, C. Roncolato +4

In order to allow a good separation of isotopes in a High Resolution Mass Spectrometer (HRMS), the transverse emittance and the energy spread of the beam should have very low value…

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…

A search for neutron-to-hidden-neutron oscillations in a ultra-cold neutron beam

G. Ban, J. Chen, P. -J. Chiu +11

Models that postulate the existence of hidden sectors address contemporary questions, such as the source of baryogenesis and the nature of dark matter. Among the possible mixing pr…

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…
