摘要：

To investigate bremsstrahlung radiation generated when the multi-layer nested Wolter-I X-ray telescope is bombarded by a high-energy electron stream, a simulation analysis using the Monte Carlo simulation software MCNP was performed to study this process (the mirror reflective film materials: Ir and Au). According to the simulation results, we found that the change of the electron incident angle has a negligible impact on the yield of the noise X-ray photons. When the incident electron energy is less than 40 keV, the energy of the generated X-ray photons is concentrated in a range below 15 keV, and the yield of noise X-ray photons is lower than the order of 10-6, which has little effect on the optical performance of the telescope.
