Fundamental neutron physics beamline at the spallation neutron source at ORNL [PDF]

Nuclear Instruments and Methods in Physics Research, Section A: Accelerators, Spectrometers, Detectors and Associated Equipment, 2015
We describe the Fundamental Neutron Physics Beamline (FnPB) facility located at the Spallation Neutron Source at Oak Ridge National Laboratory. The FnPB was designed for the conduct of experiments that investigate scientific issues in nuclear physics, particle physics, astrophysics and cosmology using a pulsed slow neutron beam.

COHERENT at the Spallation Neutron Source

Annual Review of Nuclear and Particle Science, 2023
The Spallation Neutron Source (SNS) at Oak Ridge National Laboratory provides an intense, high-quality source of neutrinos from pion decay at rest. This source was recently used for the first measurements of coherent elastic neutrino–nucleus scattering (CEvNS) by the COHERENT Collaboration, which resulted in new constraints of physics beyond the ...

Real electronic signal data from particle accelerator power systems for machine learning anomaly detection

Data in Brief, 2022
This article describes real time series datasets collected from the high voltage converter modulators (HVCM) of the Spallation Neutron Source facility. HVCMs are used to power the linear accelerator klystrons, which in turn produce the high-power radio ...
