Neutron penumbral imaging simulation and reconstruction for Inertial Confinement Fusion Experiments

Neutron penumbral imaging technique has been successfully used as the diagnosis method in Inertial Confined Fusion. To help the design of the imaging systems in the future in CHINA. We construct the Monte carlo imaging system by Geant4. Use the pointspread function from the simulation and decode algorithm (Lucy-Rechardson algorithm) we got the recovery image.
