Description
After the detection of CE$\nu$NS, the COHERENT collaboration is exploring new physics by precisely measuring the process. However, the uncertainty of the neutrino flux normalization is limiting the precision. To reduce the uncertainty, a heavy water (D$_{2}$O) detector has taken data at the Spallation Neutron Source (SNS) at Oak Ridge National Laboratory (ORNL) since 2023. By utilizing the well-understood charged-current interaction of deuterium, this D$_{2}$O detector is anticipated to reduce the flux uncertainty from 10% to less than 3% within a few years. In addition, the second module, made of water (H$_{2}$O), was recently installed to further understand the neutrino interaction with oxygen. This poster will present the status of the detectors, especially focusing on the second H$_{2}$O module installation. Their anticipated impact on the precision measurement of CE$\nu$NS will also be covered.
