The first experimental discovery of CEvNS (Coherent Elastic Neutrino-Nucleus Scattering) was made by the COHERENT Collaboration using a cesium iodide detector in 2017. Later in 2021, COHERENT also observed CEvNS on an argon target. On its own, the experimental detection of CEvNS was important because it confirmed the theoretical prediction that preceded it by more than 40 years. Now, a more detailed study of CEvNS can be used as a probe to accurately test the Standard Model. This work will discuss a brief overview of CEvNS, a review of previous experiments, the state of current detectors, and provide an outlook on planned subsystems.
