Measurement of ${}^{144}\mathrm{Pr}$ beta-spectrum with Si(Li) detectors for the purpose of determining the spectrum of electron antineutrinos

Abstract

Here we present the specifications of the newly developed beta-spectrometer based on thick full absorption Si(Li) detector. The spectrometer can be used for precision measurements of various beta-spectra, namely for the beta-spectrum shape study of ${}^{144}$Pr, which is considered to be the most promising anti-neutrino source for sterile neutrino searches.
