| Abstract: | In inertial confinement fusion(ICF) target,collision between fusion neutrons may produce super-high energy neutrons.A relationship between velocity of fusion and ratio of generated super-high energy neutron is derived.An ideal fusion model is simulated by numerical method.It indicates that the ratio of generated super-high energy neutron is increased sharply as burning volume of DT is decreased.With this information,2D-effect and mixing-effect during compression of target are deduced with escaped super-high energy neutrons.Furthermore,a relationship between velocity of burning T and ratio of generated super-high energy neutron is concluded.It shows that using super-high energy neutron to detect ICF is effective. |
