New Limits on Transformation from HFIR Cold Neutron Beam
James M. Rogers, Leah J. Broussard, Christopher B. Crawford +16
Hypothetical neutron to sterile neutron transformations would violate baryon number and point to the nature of Dark Matter. We performed a new search for $n…
Multimode structured neutron beams
Owen Lailey, Dusan Sarenac, Charles W. Clark +9
The experimental realization of neutron orbital angular momentum (OAM) states and neutron Airy beams has opened new avenues for structured neutron science in both materials charact…
Generation of neutron Airy beams
Dusan Sarenac, Owen Lailey, Melissa E. Henderson +8
The Airy wave packet is a solution to the potential-free Schrodinger equation that exhibits remarkable properties such as self-acceleration, non-diffraction, and self-healing. Alth…
Optimization of Ray-tracing Simulations to Confirm Performance of the GP-SANS Instrument at the High-Flux Isotope Reactor
James M. Rogers, Matthew J. Frost, Lisa DeBeer-Schmitt
The CG-2 beamline at the High Flux Isotope Reactor (HFIR) exhibits a notable discrepancy between observed count rates and the count rates we would expect based on a Monte-Carlo neu…
