COHERENT MicroCLEAR: Towards a Measurement of Coherent Elastic Neutrino-Nucleus Scattering on Neon

The COHERENT collaboration has measured coherent elastic neutrino-nucleus scattering (CEvNS) on CsI, argon, and most recently germanium. While efforts are underway to obtain precision measurements of CEvNS on NaI and argon with new tonne-scale detectors, the opportunity of measuring CEvNS on other liquid noble targets with the existing CENNS-10 detector is now present. A CEvNS measurement on neon will serve as a clean probe of the Standard Model, complementing current measurements of the N² dependence of the CEvNS cross-section. Neon benefits from lower systematic uncertainties due to its small nuclear form factor as well as from having zero axial vector contributions from unpaired nucleons. Neon also contains no long-lived radioisotopes, yielding lower intrinsic backgrounds, and liquid neon (LNe) has similar scintillation properties as liquid argon, requiring minimal changes to existing infrastructure. Efforts to refit the CENNS-10 detector for LNe, renamed "MicroCLEAR," began in July 2025, and a status report is presented.
