A compact high flux polarized neutron beam generator

This paper introduced a compact high flux polarized neutron beam generator scheme, which used air as the working medium and had low energy consumption. The neutron beam generator adopted a linear three compartment configuration, sequentially using nitrogen nucleus tandem near range accelerated polarization target spallation nuclear reaction technology, neutron multiplication technology, neutron beam polarization and near range acceleration technology, neutron focusing and shooting control technology. Through design and equivalent verification, it has been proven that the total length of the device does not exceed 5 meters, the effective range can reach several hundred kilometers, the neutron flux at the muzzle is not less than 10 25 n∙cm -2 ∙s -1 , which attenuates to 10 10 n∙cm -2 ∙s -1 at a distance of several 100 km, and this flux can effectively strike the target. It can be used as a defensive directed energy weapon with high energy density and has broad application prospects.
