A genetic algorithm to design Laue lenses with optimal performance for focusing hard X- and gamma-rays
摘要：
为了聚焦硬X射线和伽马射线，可以使用劳厄透镜作为聚光器。有了这种光学工具，就有可能改善对辐射的探测，用于多种应用，从观察天空中最剧烈的现象到核医学应用，用于诊断和治疗目的。一个名为劳埃根，基于遗传算法，旨在设计优化的劳埃透镜，已经实施。选择遗传算法是因为劳厄透镜的优化是一个复杂的离散化问题。输出的代码包括在设计的劳厄透镜组成的衍射晶体选择和安排，以这种方式，以最大限度地提高透镜的性能。该代码允许管理任何材料和晶体取向的晶体。程序的结构使得用户可以控制镜头的所有初始参数。因此，劳厄根是高度通用的，可用于设计非常小的镜头，如核医学，非常大的镜头，如卫星搭载的天体物理任务。
英文摘要：
In order to focus hard X- and gamma-rays it is possible to make use of a Laue lens as a concentrator. With this optical tool it would be possible to improve the detection of radiation for several applications, spanning from the observation of the most violent phenomena in the sky to nuclear medicine applications, for diagnostic and therapeutic purposes. A code named LaueGen, based on a genetic algorithm and aimed to designing optimized Laue lenses, has been implemented. The genetic algorithm was selected because the optimization of a Laue lens is a complex and discretized problem. The output of the code consists in the design of a Laue lens composed of diffracting crystals selected and arranged in such a way to maximize the performance of the lens. The code allows one to manage crystals of any material and crystallographic orientation. The program is structured in such a way that the user can control all the initial parameters of the lens. As a result, LaueGen is highly versatile and can be used for the design of very small lens, e.g. for nuclear medicine, to very large lens, e.g. for satellite-borne astrophysical missions.
