Description

The Fundamental Neutron Physics Beamline at the Spallation Neutron Source provides intense, pulsed, cold-neutron beams dedicated to fundamental physics. With the termination of the nEDM@SNS experiment, we are proposing a new strategy to develop the beamline into a multi-user facility. This would include upgrades to allow measurements of correlations in the decay of polarized neutrons with the Nab spectrometer at the primary beamline (‘pNAB’), in tandem with new instruments at the secondary monochromatic beamline. Since decay experiments like Nab transmit the majority of the neutron beam, there is potential for an extension of the primary beamline to establish another instrument station, allowing up to three simultaneous experiments.
This presentation will detail these plans and present the outcome of a recent review of the most promising future instruments that could take advantage of this expanded facility.
