New high-sensitivity search for neutron to mirror-neutron oscillations at the PSI UCN source
N. J. Ayres, Z. Berezhiani, G. Bison +19
In a search for potential signals of neutron (n) to mirror-neutron (n') oscillations, a collaboration centered at the Paul Scherrer Institute (PSI) investigated the remaining param…
Ultracold neutron energy spectrum and storage properties from magnetically induced spin depolarization
N. J. Ayres, G. Ban, G. Bison +53
We present a novel method for extracting the energy spectrum of ultracold neutrons from magnetically induced spin depolarization measurements using the n2EDM apparatus. This method…
Temperature dependent ultracold neutron transmission in D gas a test of the Young-Koppel model
G. Bison, R. Grössle, K. Kirch +4
The Young-Koppel model (YK) describes comprehensively the interaction of slow neutrons with diatomic gases such as H and D. This paper reports on the first experimental res…
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…
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…
