摘要

<正>A calibration experiment of CR-39 with Ne ions for space heavy ion identification has been performed. It is necessary for studying the mechanism of mutation breeding induced by space particles. In the experiment, 20Ne ion beams with nominal energy of 230 MeV/u and density of 500 cm-2 supplied by HIMAC were used to irradiate a stack of 25 pieces of CR-39 films vertically. After degraded by a binary filter, the
