Abstract: (Springer)

The DANSS neutrino spectrometer has been collecting data for more than four years, detecting reactor antineutrinos by means of the inverse

\beta

-decay (IBD) reaction. The experimental setup is movable being equipped with a lifting device. The analysis of the ratios of IBD positron spectra taken at different distances from the center of the reactor core makes it possible to search for the short-range oscillations of electron antineutrinos due to their transition into a hypothetical sterile state. In addition, the DANSS experiment conducts the reactor power monitoring, using the measured reactor antineutrino counting rate. The presented DANSS results on neutrino oscillations are based on more than 3.5 million IBD events, which were collected from October 2016 to February 2020. The measured positron spectra from the IBD reaction are compared with theoretical predictions. Long-term measurements of the reactor power are also presented. Their comparison with the data provided by the Kalinin NPP staff illustrates the excellent detector capacity for the independent high-precision monitoring of a nuclear reactor.
