  1. 26. ¹⁹⁹Hg Co-Magnetometer System for the n2EDM Experiment at PSI
    Nikolaus Stephan Edler von Schickh (PSI - Paul Scherrer Institut)
    02/09/2026, 09:00
    Oral Presentation

    Achieving the n2EDM baseline sensitivity of 1×10⁻²⁷ e·cm at the Paul Scherrer Institut demands precise monitoring of the magnetic field experienced by the neutrons. This is achieved using optically pumped ¹⁹⁹Hg co-magnetometers, which operate in the same storage volumes as the neutrons. Their role is crucial, as they guard against a class of systematic shifts that cannot be mitigated...

  2. 29. Implementation of a Hg comagnetometer approaching shot-noise-limited detection.
    Eric Miller (University of British Columbia)

    Oral Presentation

    The TRIUMF UltraCold Advanced Neutron collaboration recently demonstrated the world’s highest UCN density using a spallation-driven source. This milestone enables an nEDM experiment with a sensitivity goal of 10$^{−27}$ e·cm. Hg vapour co-magnetometry provides essential correction of magnetic field drifts at the picotesla level during each Ramsey resonance cycle, while also introducing...

  3. 24. Magnetic Fields Monitoring for the LANL nEDM experiment
    Antonella Saracino

    Oral Presentation

    Measurements of the neutron electric dipole moment (nEDM) provide a sensitive probe
    of CP-violating beyond the Standard Model physics. The Los Alamos National
    Laboratory (LANL) nEDM experiment is a double-cell ultracold neutron (UCN)
    experiment that aims to achieve a statistical sensitivity of 2 x 10-27 e cm, an order-of-
    magnitude smaller than the current experimental limit. To control...

  4. 40. The TUCAN Source Deuterium Neutron Moderation System
    Alexis Brossard (Triumf)
    02/09/2026, 10:15
    Oral Presentation

    Neutron cooling in the TUCAN source is achieved through a three-stages system. First, room-temperature heavy water provides thermalization. This is followed by liquid deuterium at 20 K for further cooling, and finally by isopure helium-4 at 1 K, which enables superthermal ultracold neutron (UCN) conversion.
    The liquid deuterium moderator was the final component of the source to be...
