This proposal will use ultra-high vacuum and low temperature surface techniques to simulate condensedvolatile molecules (interstellar ice analogs) in astrophysical environments in space, and use spectroscopy andmass spectrometry to monitor the evolution of ices irradiated by electron, vacuum-ultraviolet, extremeultraviolet and X-ray, respectively. Moreover, The refractory residue will be analyzed by using a highperformance liquid chromatography (HPLC) and a gas chromatography-mass spectrometry (GC-MS). Theresearch topics of this proposal include (1) the formation mechanism of organic molecules in Pluto system, (2)the photodesorption yield and photodesorption mechanism of astrophysical ice analogs, (3) spontelectric fieldof polar ices, (4) the effect of X-ray induced secondary electron on the formation mechanism of products inices, (5) X-ray irradiation of crystalline silicates. The results to be obtained from the proposed tasks willbring us understand more about the interstellar-physics and interstellar-chemistry and will, in particular,provide crucial experimental data for current and future space missions.
