Description
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 $8.1×10^{13} \overline{v_e}/cm^2s$. When combined with the $0.2 keV_{ee}$ detector threshold achieved, a first measurement of $CE𝜈NS$ 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.
