摘要

Secondary electron and X-ray emission is the main mechanism for the enegy loss of the projectile during the inelastic ion-atom collisions.The knowledge of the emission yield and cross section not only provides significant information for the basic understanding of the interaction mechanism,but also is important to the technological applications such as surface analysis in scanning electron microscopes,material modification,developments of fusion device and so on.Some works have been done to sudty separately the electron and X-ray emission[1-3].However,researches investigsting imultaneously the two phenomenon is rare.Here,we would like to present our recent experiment about the secondary emetron and X-ray emission of tungsten for proton impacting.
