This research project reveals the detail analysis of experimental conditions in space environmental simulation for establishing the highly qualitative and quantitative ground-based simulation by using the 3^<rd> generation quantum synchrotron radiation. We have obtained the following conclusions: 1. Collision energy of atoms influences the erosion of materials in simulation experiments; 2. Synergistic effect with ultraviolet does not appear on fluorinated materials; 3. Effect of neutral gases beside atomic oxygen cannot be neglected; 4. Release of hydrogen from DLC is affect by the collision energy of atomic oxygen; and 5. Protective oxide layer is formed at the Si- or Ti-doped DLC by atomic oxygen exposure. These experimental results and conclusions are obtained by the precise surface analysis with the use of synchrotron radiation and high-energy ion accelerators. Many important key points for the reliable space environmental simulation are discovered through this research project.
