Abstract

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 m, the effective range can reach several hundred kilometers, the neutron flux at the muzzle is not less than 10²⁵ n·cm⁻²·s⁻¹, which attenuates to 10¹⁰ 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.

一个紧凑的高通量极化中子束发生器

本文介绍了一种以空气为工作介质、能耗低的小型高通量极化中子束发生器方案。中子束发生器采用线性三室结构，依次采用氮核串联近程加速极化靶散裂核反应技术、中子倍增技术、中子束极化与近程加速技术、中子聚焦与射击控制技术。通过设计和等效验证，证明该装置的总长度不超过5 m，有效射程可达几百公里，枪口处的中子通量不小于1025 n·cm−2·s−1，在几百公里的距离上衰减到1010 n·cm−2·s−1，该通量可有效打击目标。它可以作为一种高能量密度的防御性定向能武器，具有广阔的应用前景。
