MIEZE（零努力强度调制）技术是中子共振自旋回波（NRSE）的一种变体，已被证明是一种独特的中子散射技术，用于在磁场中进行高能量分辨率测量。它在飞行路径差异方面的局限性已经被研究分析为中子束与消失发散。在目前的工作中，蒙特-卡罗模拟准弹性MIEZE实验考虑到光束发散以及样品尺寸。MIEZE技术的一个应用可以是瑞典欧洲空间源的专用NRSE-MIEZE仪器。在蒙特卡洛模拟的帮助下，一个特定的设计的基础上蒙泰尔镜光学的优化将在这里详细讨论。
The MIEZE (Modulation of Intensity with Zero Effort) technique is a variant of neutron resonance spin echo (NRSE), which has proven to be a unique neutron scattering technique for measuring with high energy resolution in magnetic fields. Its limitations in terms of flight path differences have already been investigated analytically for neutron beams with vanishing divergence. In the present work Monte-Carlo simulations for quasi-elastic MIEZE experiments taking into account beam divergence as well as the sample dimensions are presented. One application of the MIEZE technique could be a dedicated NRSE-MIEZE instrument at the European Spallation Source (ESS) in Sweden. The optimisation of a particular design based on Montel mirror optics with the help of Monte Carlo simulations will be discussed here in detail.
