First Results from a CEvNS Search with the CENNS-10 Liquid Argon Detector

For the COHERENT Collaboration: The COHERENT experiment recently observed Coherent Elastic Neutrino Nucleus Scattering (CEvNS) at the Spallation Neutron Source at Oak Ridge National Lab at the 6.7$\sigma$ level with 14 kg of CsI commissioned in June 2015. COHERENT is intending to measure CEvNS on multiple nuclei to verify the $N^{2}$ dependence of the CEvNS cross section. To that end, the roughly 30 kg single phase liquid argon detector CENNS-10 was commissioned in December 2016. CENNS-10 will provide a much lighter nucleus for CEvNS scattering, allowing COHERENT to begin to map out the low $N$ dependence of the CEvNS cross section. In this talk I will present preliminary results of the initial liquid argon run covering Dec. 2016 - May 2017 as well as a brief look at the current and future liquid argon program for COHERENT.
