In the characterization of ion beams using CR-39, information on ion energies, incident angles, and ion species can be extracted from the geometrical structure of the etch pits. In this study, the spatial distribution of accelerated ions has been measured by using 55 cm wide CR-39 detectors. In addition, by measuring the etch pit open mouth radius and the gray scale, the energy distributions of accelerated ions were also evaluated.
