Experimental Building – Final Design Complete

Unusual requirements for the nEDM@SNS experimental building include a magnetic keep-out zone near the apparatus and a deep basement for access to the cryogenic interior. Final design of the building was recently completed. 3D CAD model of nEDM@SNS experimental building. Drawing of the experimental building and environs from final design …

Liquefier Recovery

A helium liquefier, associated compressors and large Helium gas storage tanks were recovered from the old Alpha-2 building at Y-12 ahead of its imminent demolition. They have a new lease on life and will supply the nEDM@SNS experiment with up to 40 liters of liquid helium per hours at a …

SULI Posters

Two SULI recently completed all-virtual summer internships working on the nEDM@SNS experiment. Devon Loomis carried out simulations to optimize the design of the measurement cell windows and shielding and Michael Kline pioneered spin-tracking simulations using an array of GPUs.

Cryo B Monitor

The nEDM@SNS experiment requires a magnetic field monitor operating near absolute zero temperature. Operating at zero temperature, especially given the experiment’s metallic keep-out zone is challenging. The cryogenic magnetic field monitor was recently completed at the University of Kentucky.  

Building Updates

Building 8713 at the Spallation Neutron Source provides a home for experiments carried out at the Fundamental Neutron Physics Beamline. A recent facelift (removal of a stairway and addition of a new roll-up door) prepared the way for installation of the first nEDM@SNS equipment.
