A high intensity neutron generator, which can be used as a basis of an electronuclear facility, is described. Generation of neutrons is a result of interaction of stores deutron beam with internal thin target. The target from matter with low atomic number Z is placed in the vacuum chamber of deutron storage ring. A choice of facility parameters can create such conditions that deutron losses from coulomb and nuclear scattering in the target are minimal and almost all of deutrons give us neutrons. 9 refs.; 2 figs.; 1 tab.
