Monte-Carlo sensitivity study for sterile neutrino search with $^{144}$Ce - $^{144}$Pr source and liquid scintillation detectors of various geometries

Expected energy spectra calculations for large volume liquid scintillation detectors to inverse $β$-decay for antineutrinos produced by $^{144}$Ce -- $^{144}$Pr artificial source have been performed. The calculations were carried out through Monte-Carlo method within GEANT4.10 framework and were purposed to search for neutrino oscillation to sterile eigenstate with mass about 1 eV. The analysis of relative sensitivity to oscillation parameters for different detector shapes has been performed.

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

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.
