First results from a search for coherent elastic neutrino-nucleus scattering (CE$\nu$NS) at a reactor site

Abstract

The deployment of a low-noise 3 kg p-type point contact germanium detector at the Dresden-II power reactor, 8 meters from its 2.96 GW${}_{th}$ core, is described. This location provides an unprecedented (anti)neutrino flux of 8.1$\times 10^{13}\overline{{\nu }_e}/$cm${}^2$s. When combined with the 0.2 keV${}_{ee}$ detector threshold achieved, a first measurement of CE$\nu$NS from a reactor source appears to be within reach. We report on the characterization and abatement of backgrounds during initial runs, deriving improved limits on extensions of the Standard Model involving a light vector mediator, from preliminary data.
