中文摘要：

采用TRIM和SRIM2003软件模拟计算了10-300keV能量区间质子辐照Kapton／Al的能量传输过程．依据模拟结果选取了辐照能量参数，在室温真空条件下，采用空间综合辐照设备对Kapton／Al进行了质子辐照．借助于表面红外光谱技术，对Kapton的重要官能团特征峰做了定量分析，通过特征峰处吸光度的变化得到了典型分子键的损伤截面．平均损伤截面和电子能损的强烈依赖关系及TRIM计算结果一致说明keV质子辐照Kapton／Al的辐照损伤主要来自电子能损效应，太阳吸收比的变化趋势和模拟结果都表明在入射能量80keV附近，质子辐照Kapton／Al的辐照效应最大．

英文摘要：

The energy transfer of proton with energies of 10-300keV in Kapton/Al was simulated with TRIM and SRIM2003. Irradiating test parameter of energy was chosen based on the simulated results. The ground simulation tests of proton irradiations for Kapton/Al films were conducted by using the space synthesis irradiating facility under vacuum at room temperature. The key functional groups in the Kapton/Al films were analyzed quantitatively by means of the surface infrared spectrum technique. The damage cross section of typical molecular bonds was obtained from the variation of the absorbance at the characteristic peaks of key functional groups. The analysis results have shown that the average damage cross section is strongly dependent on the electron energy loss, which is agreement with the simulation results by TRIM. This indicates that the electron energy loss plays an important role in the damage of Kapton/Al by keV proton irradiation. From the tendency of the solar absorptance and the simulation results it can be seen that the proton irradiation effects have the maximum value near the incident energy of 80keV.
