13. External magnetic fields - mapping, monitoring and shielding

Mr Michał Rawlik (ETH Zürich)

Magnetic field control (passive and active shielding, coil design, current sources)

Oral

A measurement of the neutron electric dipole moment requires the magnetic field to be stable on a picotesla level. Yet in a typical experimental hall there are strong sources of magnetic field, nemeses of precise nEDM mesurements. A large-scale mapping, performed prior to the installation of the apparatus, can resolve the spatial distribution of the field. During the nEDM measurement the...

15. R&D on field stability and uniformity for the TRIUMF nEDM experiment

Prof. Christopher Bidinosti (University of Winnipeg)

Magnetic field control (passive and active shielding, coil design, current sources)

Oral

The TRIUMF nEDM experiment employs a magnetically shielded Ramsey Resonance based EDM apparatus employing ultracold neutrons from a spallation based isopure Helium-II UCN source that is currently under construction at TRIUMF. Fluctuations and inhomogeneities of the roughly 1-uT measurement field are expected to be one of the leading sources of systematic errors in the experiment. This...

37. Production of highly uniform magnetic field for the n2EDM experiment at the Paul Sherrer Institute.

Mr Pierrick Flaux (LPC Caen)

Magnetic field control (passive and active shielding, coil design, current sources)

Oral

This work presents a preliminary design of the coils system developped for the neutron electric dipole moment experiment (n2EDM) at the Paul Sherrer Institute (PSI). The goal of this experiment is to find new sources of CP violation through the measurement of the neutron electric dipole. The current best limit of the nEDM measurement, 2.9 $\times$ 10$^{ -26}$ e.cm (90% C.L.) was reached...
