Measurement of the neutron incoherent scattering length of Hg using stored ultracold neutrons

C. Abel, K. Bodek, E. Chanel +35

We present the first direct measurement of the neutron incoherent scattering length of Hg. The measurement was performed with the Ramsey apparatus of the neutron electric…

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…

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…

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…

Determination of diffusion coefficients of mercury atoms in various gases from longitudinal spin relaxation in magnetic gradients

B. Clément, M. Guigue, A. Leredde +4

We present a method to measure the binary diffusion coefficient of mercury atoms in a gas at room temperature and low pressure. It is based on the measurement of the longitudinal s…

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…
