摘要
针对自由电子激光、同步辐射光束线以及惯性约束聚变、极端条件物理过程等X射线光学系统, 开发了具有独立知识产权的光学设计仿真软件X-LAB。基于光学衍射算法和序列式光线追迹算法, 该软件集光线追迹仿真、矢量衍射仿真和复杂微结构特征光学元件版图绘制等功能, 具有界面友好、操作便捷、包含特殊光学模块、支持“用户定制”功能等特点, 为开展X射线光学系统、光学元件概念设计、优化和研制提供了不可或缺的平台。目前, X-LAB成功应用于能谱分辨率优于1000、能谱范围10~100 eV的北京同步辐射3B1无谐波单色化束线设计中及空间分辨优于6 μm, 视场500 μm的惯性约束聚变物理过程X射线诊断光学系统——K-B镜系统的设计和优化中; 具有复杂微结构光子筛版图绘制功能。
Abstract
To design the monochorator beamlines of synchrotron radiation, develop X-FELs and make X-ray diagnoses of inertia confinement fusion as well as simulate dynamic process in extreme physical conditions, a useful tool and a platform, X-LAB, for optical design, optimization and simulation with the independent intellectual property rights was developed. With friendly interface, X-LAB has the functions of sequence ray-tracing, vector diffraction simulation and layout drawing of complex micro-structure optical elements. Also, it is easy to operate and can provide accustomed service, characteristic functions for users to freely design, optimize an optical system. Currently, X-LAB has been applied in designs and simulations of the 3B1 monochromatic beamline in Beijing Synchrotron Radiation Facility with spectral resolution 1000 and spectral range 10~100 eV, the X-ray diagnosis optical systems of inertia confinement fusion and dynamic process in extreme physical conditions, the KB microscope with spatial resolution up to 6 μm, and the layout drawing of photon sieves.
