Generating a highly uniform magnetic field inside the magnetically shielded room of the n2EDM experiment
C. Abel, N. J. Ayres, G. Ban +63
We present a coil system designed to generate a highly uniform magnetic field for the n2EDM experiment at the Paul Scherrer Institute. It consists of a main coil and a set of…
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…
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…
Measurement of the permanent electric dipole moment of the neutron
C. Abel, S. Afach, N. J. Ayres +81
We present the result of an experiment to measure the electric dipole moment (EDM) of the neutron at the Paul Scherrer Institute using Ramsey's method of separated oscillating magn…
Data blinding for the nEDM experiment at PSI
N. J. Ayres, G. Ban, G. Bison +42
Psychological bias towards, or away from, a prior measurement or a theory prediction is an intrinsic threat to any data analysis. While various methods can be used to avoid the bia…
Improved determination of the - angular correlation coefficient in free neutron decay with the SPECT spectrometer
M. Beck, F. Ayala Guardia, S. Baeßler +15
We report on a precise measurement of the electron-antineutrino angular correlation ( coefficient) in free neutron beta-decay from the SPECT experiment. The coefficient i…
Characterization of the new Data Acquisition System and the detector alignment of the aSPECT experiment
Romain Virot
From April 2013 to the beginning of August 2013, the aSPECT spectrometer was installed on a cold neutron beam facility at the Institut Laue-Langevin (ILL) in order to realize a hig…
Design of the Magnet System of the Neutron Decay Facility PERC
Xiangzun Wang, Carmen Ziener, Hartmut Abele +27
The PERC (Proton and Electron Radiation Channel) facility is currently under construction at the research reactor FRM II, Garching. It will serve as an intense and clean source of…
nEDM experiment at PSI: data-taking strategy and sensitivity of the dataset
C. Abel, N. J. Ayres, G. Ban +40
We report on the strategy used to optimize the sensitivity of our search for a neutron electric dipole moment at the Paul Scherrer Institute. Measurements were made upon ultracold…
Magnetic field uniformity in neutron electric dipole moment experiments
C. Abel, N. Ayres, T. Baker +53
Magnetic field uniformity is of the utmost importance in experiments to measure the electric dipole moment of the neutron. A general parametrization of the magnetic field in terms…
The n2EDM experiment at the Paul Scherrer Institute
C. Abel, N. J. Ayres, G. Ban +45
We present the new spectrometer for the neutron electric dipole moment (nEDM) search at the Paul Scherrer Institute (PSI), called n2EDM. The setup is at room temperature in vacuum…
Statistical sensitivity of the nEDM apparatus at PSI to neutron mirror-neutron oscillations
C. Abel, N. Ayres, G. Bison +33
The neutron and its hypothetical mirror counterpart, a sterile state degenerate in mass, could spontaneously mix in a process much faster than the neutron -decay. Two groups hav…
