| 英文摘要 | A beam line dedicated to high-energy electron radiography experimental research with linear achromat and imaging lens systems has been designed. the field of view requirement on the target and the beam angle-position correlation correction can be achieved by fine-tuning the fields of the quadrupoles used in the achromat in combination with already existing six quadrupoles before the achromat. the radiography system is designed by fully considering the space limitation of the laboratory and the beam diagnostics devices. two kinds of imaging lens system, a quadruplet and an octuplet system are integrated into one beam line with the same object plane and image plane but with different magnification factor. the beam angle-position correlation on the target required by the imaging lens system and the aperture effect on the images are studied with particle tracking simulation. it is shown that the aperture position is also correlated to the beam angle-position on the target. with matched beam on the target, corresponding aperture position and suitable aperture radius, clear pictures can be imaged by both lens systems. the aperture is very important for the imaging. the details of the beam optical requirements, optimized parameters and the simulation results are presented.
