Measurement of Electron-Neutrino Charged-Current Cross Sections on I127 with the COHERENT NaIνE Detector

P. An, C. Awe, P. S. Barbeau, B. Becker et autres

Using an 185-kg NaI[Tl] array, COHERENT has measured the inclusive electron-neutrino charged-current cross section on $^{127}\mathrm{I}$ with pion decay-at-rest neutrinos produced by the Spallation Neutron Source at Oak Ridge National Laboratory. Iodine is one the heaviest targets for which low-energy ($\ensuremath{\le}50\text{ }\text{ …

First Probe of Sub-GeV Dark Matter beyond the Cosmological Expectation with the COHERENT CsI Detector at the SNS

D. Akimov, Peng An, C. Awe, P. S. Barbeau et autres

The COHERENT Collaboration searched for scalar dark matter particles produced at the Spallation Neutron Source with masses between 1 and 220 MeV/c^{2} using a CsI[Na] scintillation detector sensitive to nuclear recoils above 9 keV_{nr}. No evidence for dark matter is found and …

Measurement of ${}^{nat}$Pb($ν_e$,X$n$) production with a stopped-pion neutrino source

COHERENT Collaboration, Peng An, C. Awe, P. S. Barbeau et autres

Using neutrinos produced at the Spallation Neutron Source (SNS) at Oak Ridge National Laboratory (ORNL), the COHERENT collaboration has studied the Pb($ν_e$,X$n$) process with a lead neutrino-induced-neutron (NIN) detector. Data from this detector are fit jointly with previously collected COHERENT data on …

Measurement of scintillation response of CsI[Na] to low-energy nuclear recoils by COHERENT

D. Akimov, Peng An, C. Awe, P. S. Barbeau et autres

Abstract We present results of several measurements of CsI[Na] scintillation response to 3–60 keV energy nuclear recoils performed by the COHERENT collaboration using tagged neutron elastic scattering experiments and an endpoint technique. Earlier results, used to estimate the coherent elastic neutrino-nucleus scattering …

Measurement of the Coherent Elastic Neutrino-Nucleus Scattering Cross Section on CsI by COHERENT

D. Akimov, Peng An, C. Awe, P. S. Barbeau et autres

We measured the cross section of coherent elastic neutrino-nucleus scattering (CEvNS) using a CsI[Na] scintillating crystal in a high flux of neutrinos produced at the Spallation Neutron Source at Oak Ridge National Laboratory. New data collected before detector decommissioning have more than …

Simulating the neutrino flux from the Spallation Neutron Source for the COHERENT experiment

D. Akimov, Peng An, C. Awe, P. S. Barbeau et autres

The Spallation Neutron Source (SNS) at Oak Ridge National Laboratory is a pulsed source of neutrons and, as a by-product of this operation, an intense source of pulsed neutrinos via stopped-pion decay. The COHERENT collaboration uses this source to investigate coherent elastic …
