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…

High-Density Ultracold Neutron Source for Low-Energy Particle Physics Experiments

Skyler Degenkolb, Estelle Chanel, Simon Baudoin +19

SuperSUN, a new superthermal source of ultracold neutrons (UCN) at the Institut Laue-Langevin, exploits inelastic scattering of neutrons in isotopically pure superfluid He at t…

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…

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 an interaction mediated by axion-like particles with ultracold neutrons at the PSI

N. J. Ayres, G. Bison, K. Bodek +44

We report on a search for a new, short-range, spin-dependent interaction using a modified version of the experimental apparatus used to measure the permanent neutron electric dipol…

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…

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…

Revisiting RGEs for general gauge theories

Ingo Schienbein, Florian Staub, Tom Steudtner +1

We revisit the renormalisation group equations (RGE) for general renormalisable gauge theories at one- and two-loop accuracy. We identify and correct various mistakes in the litera…
