RESTRAX是一个先进的中子光学系统光线追迹模拟软件包。本章回顾了其高效的光线跟踪代码所使用的技术,即采样策略,数值优化和用于模拟通过中子光学元件运输的随机行走技术的细节。此外,还简要介绍了三轴中子谱仪分辨函数和模型谱的光线追迹模拟。
RESTRAX is an advanced software package for raytrace simulations of neutron optical systems. This chapter reviews the techniques used by its efficient raytrace code, namely sampling strategy, numerical optimizations and details of the random-walk technique used to simulate transport through neutron optical components. In addition, raytrace simulations of resolution functions and model spectra for three-axis neutron spectrometers are briefly described.
