Abstract content

A 185 kg NaI[Tl] detector has been deployed to the Spallation Neutron Source (SNS) at Oak Ridge National Laboratory (ORNL) to measure the charged-current neutrino interaction cross section on $^{127}$I. Results from an initial run will be shown, as well as improvements from a recent upgrade in which muon vetos were deployed to reduce backgrounds. In addition to measuring the charged-current interaction, the 185 kg detector is also measuring low energy backgrounds in the region of interest for observing coherent elastic neutrino-nucleus scattering of $^{23}$Na nuclei. A tonne-scale version of the detector is currently being developed with the capability to simultaneously observe these two interactions.
