Proton radiography: its uses and resolution scaling

摘要

Modem proton radiography(pRad),which was invented at the Los Alamos National Laboratory(lanl),is especially well suited for investigation of dense materials.When compared to x-radiography,the mean free path of protons is much longer resulting in near-optimum radiographic transmission. The proton radiography facility at LANLwhich utilizes the 800 MeV proton beam at the Los Alamos Neutron Sciences Center(LANSCE),is a user facility mainly serving the weapons community.
