Energy Transfer of keV Proton in Kapton/Al

  • 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.

Abstract: 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.
