METHOD FOR PRODUCING ISOTOPE USED TO CALIBRATE RADIOCHEMICAL NEUTRINO DETECTORS Russian patent published in 1997 - IPC

Abstract RU 2092920 C1

FIELD: radiochemistry. SUBSTANCE: target made of enriched nitrogen is irradiated by alpha-particle flux with flux density higher than or equal to 1017 alpha-particles, m-2•c-1 and 34S concentration higher than or equal to 1028 atoms in 1 cu.m. Constant neutrino flux is obtained from neutrino source based on isotope 37Ar at constant volume activity higher than or equal to 3,7•10. EFFECT: provision for producing constant neutron flux.
