In order to identify the density and material type, high energy protons, electron, and heavy ions are used to radiograph dense objects. The transmitted particles through the object undergo the multiple coulomb scattering, and focus on an image plane by a magnetic lens system. A transformed beam line in the Institute of Modern Physics (IMP) of the Chinese Academy of Sciences (CAS) has been developed for heavy ions radiography. It can radiograph a static object and the spatial resolution is about 65um (σ). This paper presents the heavy ions radiography facility at IMP, including the beam optics, the simulation of radiography by Monte Carlo code and the experiment result with 600 MeV/u carbon ions. In addition, the dedicated beam lines for proton radiography in plan are also introduced.
