Description

As part of the COHERENT collaboration’s efforts toward precision CEvNS measurements since the first observation in 2017, COH-Ar-750 is the upcoming ton-scale liquid argon detector at Neutrino Alley, located at the Oak Ridge National Laboratory’s Spallation Neutron Source (ORNL SNS). It will replace its smaller predecessor, the CENNS-10 detector, which first observed CEvNS on argon in 2019 and has since collected over three times the data reported in its initial publication. In this presentation, I will discuss the current status of the COH-Ar-750 detector and the ongoing efforts aimed at a first engineering run in 2026. I will also present progress toward a final CENNS-10 analysis based upon dataset with triple the integrated beam power of the original observation.
