    1. 39. n2EDM Vacuum System
      Rolf José Koch (PSI - Paul Scherrer Institut)
      03/09/2026, 16:30
      Oral Presentation

      The n2EDM experiment at PSI searches for the neutron electric dipole moment using stored ultracold neutrons. Its vacuum and gas system must
      simultaneously support UCN storage, high-voltage stability, the ¹⁹⁹Hg
      comagnetometer, helium buffer-gas operation, and discharge cleaning. I
      present an overview of the system and its recent automation: a state
      machine that reduces operation to...

    2. 55. EDMs, light scalars, and their interplay
      David McKeen (TRIUMF)
      03/09/2026, 16:55
      Oral Presentation

      I will discuss EDMs and their connection to theories of light scalars. These scalars can lead to nontrivial structures that develop during the evolution of the Universe. Such scalars can be searched for with experiments targeting EDMs as well as other precision measurements.

    3. 9. Degaussing optimization for the magnetically shielded room (MSR) of the TUCAN EDM experiment at TRIUMF
      Anthony Lejuez (TRIUMF)
      03/09/2026, 17:20
      Oral Presentation

      The search for the neutron electric dipole moment (nEDM) with the TUCAN experiment at TRIUMF requires a well-controlled magnetic environment, in which both the residual magnetic field and its spatial gradients are minimized. This is provided by a MSR (with a shielding factor of 60 000 at 0.01Hz), which serves as the central infrastructure for generating and maintaining the low-magnetic-field...

    4. 11. Superconducting shielding commission for nEDM@SNS
      Xiaozhe Zhu (California Institute of Technology)
      03/09/2026, 17:45
      Oral Presentation

      Achieving nT/m-level magnetic-field uniformity and isolating the time-dependent field noise inside the measurement cells of the nEDM@SNS experiment requires additional magnetic shielding around the magnet package. In this talk, I will present the design and performance of a superconducting lead shield developed for the experiment. The shield uses a modular geometry that is installed around the...
