Description
The Spallation Neutron Source (SNS), used by the COHERENT experiment as a source of neutrinos to measure CE$\nu$NS cross section, produces $\nu_e$, $\nu_{\mu}$, and $\bar{\nu}_{\mu}$ in energy ranges of a few tens of MeV. A heavy water Cherenkov detector is under construction to measure this neutrino flux in support of CE$\nu$NS measurement. The heavy water detector can also be used to measure the cross section of neutrino-nucleus charged-current interactions on $^{16}O$ nuclei. Charged-current $^{16}O(\nu_e,e^-)X$ reactions produce recoiling $e^-$ that will emit Cherenkov radiation within the detector with an energy threshold of about 15 MeV, well within the energy range of $\nu_e$ created at SNS. This charged-current reaction in oxygen has never been measured and has implications for supernovae neutrino detection and testing nuclear physics theories. This poster describes methodology for detecting and measuring the cross section and event rate of this charged-current interaction between $\nu_e$ and $^{16}O$ nuclei.
