Research Abstract

The development of CdWO4 crystal scintillator sensitive to low-energy anti-neutrinos emitted by Potassium nucleus decays was performed to measure the radiogenic heat contribution in Earth's heat production, and its performance was evaluated. The prototype detector based on measured parameters was already designed, and built a realistic technic for a new anti-neutrino detection device. As a consequence, the study has reached the stage to start to discuss a plan for a future large detector to measure the Potassium anti-neutrino flux at about 20% uncertainty.
