39. n2EDM Vacuum System

Rolf José Koch (PSI - Paul Scherrer Institut)

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...

11. Superconducting shielding commission for nEDM@SNS

Xiaozhe Zhu (Graduate Student)

03/09/2026, 16:55

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...

9. Degaussing optimization for the magnetically shielded room (MSR) of the TUCAN EDM experiment at TRIUMF

Anthony Lejuez (TRIUMF)

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...
