OBSERVING METHOD OF NUCLEAR REACTOR NEUTRINOS BY CAPACITOR-TYPE HYDROGEN ION BEAM SOURCE

摘要

PROBLEM TO BE SOLVED: To provide a method with which variations in hydrogen ions or a deuterium ions and a secondary generated particles are observed through making nuclear reactor neutrinos pass along the hydrogen ion beam or the deuterium ion beam.;SOLUTION: Anti-electron neutrinos ν_e* from a nuclear reactor is received by the positive hydrogen ion H⁺ beam which has a high-energy orientation, and the following interaction is performed: ν_e* + H⁺ (positive hydrogen ion) → e⁺ (positive electron) + n (neutron). In this case, the orientations of the beams of ν_e* and H⁺ are made to coincide. Acceleration is conducted so as to make the momentum of H⁺ become larger than that of e⁺. A 90-degree bend magnetic field mass spectrometer is arranged after the H⁺ beam. The current density of e⁺ is detected nearly at a total flow rate of ν_e* (10¹¹/cm² sec). A method which utilizes polarization of hydrogen molecules adsorbed spontaneously on the insulation film surface of a capacitor is used, with the H⁺ beam being generated easily and at low cost, and the H⁺ beam can be directed easily in the direction of a nuclear power plant.;COPYRIGHT: (C)2004,JPO&NCIPI
