Light Collection Readout Production Electronics Tested

The nEDM@SNS experimental signal is a burst of scintillation light following the capture of a neutron by a Helium-3 nucleus. Processing electronics that use silicon photomultipliers to count the number of emitted photons and record their arrival time have now been completely tested.

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

Cryovessel Design Complete

The final design of the nEDM@SNS Cryovessel (a large aluminum vacuum vessel which functions effectively like a giant thermos) was recently completed. Long-leadtime components are being ordered and fabrication will be starting imminently.

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.
