Query: Coherent elastic nuclear scattering of $^{51}$Cr neutrinos   Searches for new physics in the coherent elastic neutrino-nucleus scattering
require a precise knowledge of the neutrino flux and energy spectrum. In this
paper we investigate the feasibility and the performances of an experiment
based on a $^{51}$Cr source, whose neutrino spectrum is known and whose
activity can be heat-monitored at few permil level. With a 5 MCi source placed
at ~ 25 cm from the detector, under an exposure of two $^{51}$Cr half-lives
(55.4 days), we evaluate 3900 (900) counts on a 2000 cm$^3$ target of germanium
(sapphire) featuring an energy threshold of 8 (20) eV. To further increase the
exposure, multiple activations of the same source could be possible.
