Coherent neutrino nucleus scattering (CNNS) has so far not been observed experimentally. In the present work the feasibility of a first observation of CNNS using low-temperature detectors is studied. A measured background spectrum is compared to simulated spectra of different background sources. The measurements were performed using a sapphire-based low-temperature detector. Furthermore, the calculated count rates and recoil-energy spectra of different neutrino sources are shown. As a result of the measurements, simulations, and calculations a first observation of CNNS is possible using sapphire-based low-temperature detectors and nuclear reactors as neutrino sources. In addition, the investigation of physics beyond the standard model is studied. Due to their calculated count rates atmospheric and also solar neutrinos can constitute an ultimate background source for direct dark matter searches.
