Simulation of D³He fusion monoenergetic proton radiography of ICF implosions

The quasi-monoenergetic beam of 14.7 MeV D3He-fusion protons generated by laser implosion has very important application in proton radiography. Using the FLUKA Monte Carlo code, this paper simulates the diagnosis of the implosions by protons. The simulation focuses on the effect of proton number on imaging quality, proton radiography of direct-driven implosion and indirect-driven implosion, and proton radiography at different time during implosions. The result indicates that the beam of 14.7 MeV D3He-fusion protons is quasi-monoenergetic and small sized, and can be used in the dynamic radiography of ICF implosions.
