【摘要】 脉冲星X射线会聚方案成为制约脉冲星导航精度的关键因素,本文基于龙虾眼掠入射会聚原理,在国内率先开展了用于脉冲星导航的新型微孔光学元件—玻璃基底X射线微孔光学元件(MPO)的研究与试制。文章分析了不同波段X射线照射时MPO能发生二次掠入射全反射和一次掠入射全反射的有效面积,研制了MPO样片。样片在1.49ke V平行光及8.05ke V平行光照射时呈现清晰的十字焦斑,十字焦斑长度分别为30mm、17mm,焦斑中心强度明显高于十字臂,与全反射有效区域的理论推导一致。此外,8.05ke V平行光照射MPO样片角分辨率为4.19’,聚焦效果明显。更多还原

【Abstract】 Solutions of focusing pulsars X-ray become a restriction to the accuracy of pulsar navigation. Based on the focusing principle of lobster eye grazing incidence, this article expounds the research and developm ent of new micro pore optics for pulsar navigation which is X-ray micro pore optics(MPO). First of all, the effective area on MPO when first grazing incidence happens and second grazing incidence happens is analyzed in detail. Then we made the first generation of MPO. The MPO has been illum inat ed by parallel X-ray beam of 1.49 ke Vand 8.05 ke V. Both the results show a clear cross focusing image on the X-ray film or detector. The arms of cross image of 1.49 ke Vand 8.05 ke Vare respectively 30 mm and 17 mm in length, and the center intensity was signif icantly higher than the cross arm which is consistent withtheoretical calculation. Bes ides, the angular resolution of first generation of MPO with 8.05 ke V parallel X-ray beam illum inated is 4.19’.更多还原
