Ptychographic X-ray imaging at the highest spatial resolution requires an optimal experimental environment, providing a high coherent flux, excellent mechanical stability and a low background in the measured data. This requires, for example, a stable performance of all optical components along the entire beam path, high temperature stability, a robust sample and optics tracking system, and a scatter-free environment. This contribution summarizes the efforts along these lines to transform the nanoprobe station on beamline P06 (PETRA III) into the ptychographic nano-analytical microscope (PtyNAMi).
在最高空间分辨率下进行叠层X射线成像需要一个优化的实验环境，以提供高相干通量、出色的机械稳定性以及测量数据中的低背景。例如，这需要沿整个光路的所有光学元件具有稳定的性能、高温稳定性、强大的样品和光学跟踪系统以及无散射环境。本文总结了为将束线P06（PETRA III）上的纳米探针站转变为叠层纳米分析显微镜（PtyNAMi）而在这些方面所做的努力。
