Proton radiography is used for advanced hydrotesting as a new typeradiography technology due to its powerful penetration capability and highdetection efficiency. A new proton radiography terminal will be developed toradiograph static samples at Institute of Modern Physics of Chinese Academy ofScience (IMP-CAS). The proton beam with the maximum energy of 2.6 GeV will beproduced by Heavy Ion Research Facility in Lanzhou-Cooling Storage Ring(HIRFL-CSR). The proton radiography terminal consists of the matching magneticlens and the Zumbro lens system. In this paper, the design scheme and all opticparameters of this beam terminal for 2.6GeV proton energy are presented bysimulating the beam optics using WINAGILE code. My-BOC code is used to test theparticle tracking of proton radiography beam line. Geant4 code and G4beamlinecode are used for simulating the proton radiography system. The results showthat the transmission efficiency of proton without target is 100%, and theeffect of secondary particles can be neglected. In order to test this protonradiography system, the proton images for an aluminum plate sample with tworectangular orifices and a step brass plate sample are respectively simulatedusing Geant4 code. The results show that the best spatial resolution is about36{\mu}m, and the differences of the thickness is not greater than 10%.
