摘要

The concept of gravity-driven Dense Granular Target(DGT)has been proposed and tungsten granule is one of the candidate target materials[1].With the increase of DGT diameter,the efficiency of its external neutrons is significantly reduced,which is not conducive to the design of high-power.Low density porous tungsten particles are proposed as the target material of DGT instead of the natural tungsten.The results show that there is an optimal combination of tungsten granular density and target diameter to make the utmost of leakage neutrons.
