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…

Optically Pumped Cs Magnetometers Enabling a High-Sensitivity Search for the Neutron Electric Dipole Moment

C. Abel, S. Afach, N. J. Ayres +57

An array of sixteen laser-pumped scalar Cs magnetometers was part of the neutron electric dipole moment (nEDM) experiment taking data at the Paul Scherrer Institute in 2015 and 201…

A fast-switching magnet serving a spallation-driven ultracold neutron source

S. Ahmed, E. Altiere, T. Andalib +47

A fast-switching, high-repetition-rate magnet and power supply have been developed for and operated at TRIUMF, to deliver a proton beam to the new ultracold neutron (UCN) facility.…

A beamline for fundamental neutron physics at TRIUMF

S. Ahmed, T. Andalib, M. J. Barnes +44

This article describes the new primary proton beamline 1U at TRIUMF. The purpose of this beamline is to produce ultracold neutrons (UCN) for fundamental-physics experiments. It del…

First ultracold neutrons produced at TRIUMF

S. Ahmed, E. Altiere, T. Andalib +50

We installed a source for ultracold neutrons at a new, dedicated spallation target at TRIUMF. The source was originally developed in Japan and uses a superfluid-helium converter co…

Theory of the n=2 levels in muonic helium-3 ions

Beatrice Franke, Julian J. Krauth, Aldo Antognini +3

The present knowledge of Lamb shift, fine-, and hyperfine structure of the 2S and 2P states in muonic helium-3 ions is reviewed in anticipation of the results of a first measuremen…
